{{main|hiQ Labs v. LinkedIn}}

In May 2017, LinkedIn sent a Cease-And-Desist letter to hiQ Labs, a Silicon Valley startup that collects data from public profiles and provides analysis of this data to its customers. The letter demanded that hiQ immediately cease "scraping" data from LinkedIn's servers, claiming violations of the CFAA (Computer Fraud and Abuse Act) and the DMCA (Digital Millennium Copyright Act). In response hiQ sued LinkedIn in the Northern District of California in San Francisco, asking the court to prohibit LinkedIn from blocking its access to public profiles while the court considered the merits of its request. The court served a preliminary injunction against LinkedIn, which was then forced to allow hiQ to continue to collect public data. LinkedIn appealed this ruling; in September 2019, the appeals court rejected LinkedIn's arguments and the preliminary injunction was upheld. The dispute is ongoing.

The basic functionality of LinkedIn allows users to create profiles, which for employees typically consist of a curriculum vitae describing their work experience, education and training, skills, and a personal photo. Employers can list jobs and search for potential candidates. Users can find jobs, people and business opportunities recommended by someone in one's contact network. Users can save jobs that they would like to apply for. Users also have the ability to follow different companies.

The site also enables members to make "connections" to each other in an online social network which may represent real-world professional relationships. Members can invite anyone to become a connection. Users can obtain introductions to the connections of connections (termed second-degree connections) and connections of second-degree connections (termed third-degree connections).

A member's list of connections can be used in a number of ways. For example, users can search for second-degree connections who work at a company they are interested in, and then ask a specific first-degree connection in common for an introduction.{{cite news |last=Spiegel |first=Linda |title=How Job Hunters Should Use LinkedIn Second-Degree Connections |url=https://blogs.wsj.com/experts/2016/06/01/how-job-hunters-should-use-linkedin-second-degree-connections/ |date=June 1, 2016 |work=The Wall Street Journal |access-date=June 27, 2016 |archive-date=June 26, 2016 |archive-url=https://web.archive.org/web/20160626034413/http://blogs.wsj.com/experts/2016/06/01/how-job-hunters-should-use-linkedin-second-degree-connections/ |url-status=live }} The "gated-access approach" (where contact with any professional requires either an existing relationship, or the intervention of a contact of theirs) is intended to build trust among the service's users.

LinkedIn 'applications' often refer to external third-party applications that interact with LinkedIn's developer API. However, in some cases, it could refer to sanctioned applications featured on a user's profile page.

In February 2015, LinkedIn released an updated terms of use for their developer API.[https://developer.linkedin.com/legal/api-terms-of-use Terms of Use] {{Webarchive|url=https://web.archive.org/web/20161220035136/https://developer.linkedin.com/legal/api-terms-of-use |date=December 20, 2016 }}, LinkedIn, February 12, 2015 The developer API allows both companies and individuals the ability to interact with LinkedIn's data through creation of managed third-party applications. Applications must go through a review process and request permission from the user before accessing a user's data.

Among the initial applications were an Amazon Reading List that allows LinkedIn members to display books they are reading, a connection to Tripit, and a Six Apart, WordPress and TypePad application that allows members to display their latest blog postings within their LinkedIn profile.[http://www.businessweek.com/the_thread/techbeat/archives/2008/10/linkedin_launch.html Facebook in a Suit: LinkedIn Launches Applications Platform] {{webarchive |url=https://web.archive.org/web/20090123190641/http://www.businessweek.com/the_thread/techbeat/archives/2008/10/linkedin_launch.html |date=January 23, 2009 }}, Business Week, October 28, 2008 In November 2010, LinkedIn allowed businesses to list products and services on company profile pages; it also permitted LinkedIn members to "recommend" products and services and write reviews.[http://www.clickz.com/clickz/news/1866328/linkedin-adopts-recommend "LinkedIn Adopts 'Recommend' Over 'Like'"] {{Webarchive|url=https://web.archive.org/web/20101105102126/http://www.clickz.com/clickz/news/1866328/linkedin-adopts-recommend |date=November 5, 2010 }}, Clickz.com, November 2, 2010 Shortly after, some of the external services were no longer supported, including Amazon's Reading List.{{citation needed|date=August 2019}}

A mobile version of the site was launched in February 2008 and made available in six languages: Chinese, English, French, German, Japanese and Spanish.{{cite news |publisher=tweakers.net |url=http://life.tweakers.net/nieuws/52094/social-networkingsite-linkedin-introduceert-mobiele-versie.html |title=Social-networking site LinkedIN introduces mobile version |access-date=February 25, 2008 |archive-date=February 26, 2008 |archive-url=https://web.archive.org/web/20080226164309/http://life.tweakers.net/nieuws/52094/social-networkingsite-linkedin-introduceert-mobiele-versie.html |url-status=live }} In January 2011, LinkedIn acquired CardMunch, a mobile app maker that scans business cards and converts into contacts.[http://shoutex.com/blog/cardmunch-iphone-app-for-business-users/ CardMunch acquired by LinkedIn] {{Webarchive|url=https://web.archive.org/web/20110313023507/http://shoutex.com/blog/cardmunch-iphone-app-for-business-users/ |date=March 13, 2011 }}, shoutEx.com Feb 2011 In June 2013, CardMunch was noted as an available LinkedIn app. In October 2013, LinkedIn announced a service for iPhone users called "Intro", which inserts a thumbnail of a person's LinkedIn profile in correspondence with that person when reading mail messages in the native iOS Mail program.{{cite web |url=http://engineering.linkedin.com/mobile/linkedin-intro-doing-impossible-ios |title=Announcement |publisher=Engineering.linkedin.com |date=October 23, 2013 |access-date=December 5, 2013 |archive-date=December 4, 2013 |archive-url=https://web.archive.org/web/20131204231254/http://engineering.linkedin.com/mobile/linkedin-intro-doing-impossible-ios |url-status=live }} This is accomplished by re-routing all emails from and to the iPhone through LinkedIn servers, which security firm Bishop Fox asserts has serious privacy implications, violates many organizations' security policies, and resembles a man-in-the-middle attack.{{cite web |last=Fox |first=Bishop |url=http://www.bishopfox.com/blog/2013/10/linkedin-intro/ |title=LinkedIn 'Intro'duces Insecurity |publisher=Bishop Fox |date=October 23, 2013 |access-date=October 6, 2015 |archive-date=October 7, 2015 |archive-url=https://web.archive.org/web/20151007000922/http://www.bishopfox.com/blog/2013/10/linkedin-intro/ |url-status=live }}{{cite web |last=Fox |first=Bishop |url=http://www.bishopfox.com/blog/2013/11/introspection-intro-security/ |title=An Introspection On Intro Security |publisher=Bishop Fox |date=November 1, 2013 |access-date=October 6, 2015 |archive-date=October 6, 2015 |archive-url=https://web.archive.org/web/20151006232210/http://www.bishopfox.com/blog/2013/11/introspection-intro-security/ |url-status=live }}

LinkedIn also supports daily the formation of interest groups. In 2012, there were 1,248,019 such groups whose membership varies from 1 to 744,662.{{cite web |url=http://www.linkedin.com/groupsDirectory?results=&pplSearchOrigin=GLHD&keywords= |title=Groups Directory |publisher=LinkedIn |access-date=December 8, 2011}}{{cite news |publisher=i-newswire.com |url=http://www.i-newswire.com/world-s-largest-linkedin-group/160028 |title=World's Largest LinkedIn Group Breaks The 700,000 Member mark |access-date=February 28, 2012 |archive-date=April 17, 2012 |archive-url=https://web.archive.org/web/20120417021437/http://www.i-newswire.com/world-s-largest-linkedin-group/160028 |url-status=live }} Groups support a limited form of discussion area, moderated by the group owners and managers.{{cite web |url=http://socialmediatoday.com/mark-lerner/2070731/how-avoid-linkedin-s-site-wide-automatic-moderation |title=How to Avoid LinkedIn's Site Wide Automatic Moderation (SWAM) |website=Socialmediatoday.com |access-date=October 17, 2014 |archive-url=https://web.archive.org/web/20140627130825/http://socialmediatoday.com/mark-lerner/2070731/how-avoid-linkedin-s-site-wide-automatic-moderation |archive-date=June 27, 2014 |url-status=dead }} Groups may be private, accessible to members only or may be open to Internet users in general to read, though they must join in order to post messages. Since groups offer the functionality to reach a wide audience without so easily falling foul of anti-spam solutions, there is a constant stream of spam postings, and there now exists a range of firms who offer a spamming service for this very purpose.

LinkedIn maintains an internal knowledge graph of entities (people, organizations, groups) that helps it connect everyone working in a field or at an organization or network. This can be used to query the neighborhood around each entity to find updates that might be related to it.{{Cite web|title=Building The LinkedIn Knowledge Graph|url=https://engineering.linkedin.com/blog/2016/10/building-the-linkedin-knowledge-graph|access-date=July 1, 2020|website=engineering.linkedin.com|language=en|archive-date=September 22, 2020|archive-url=https://web.archive.org/web/20200922220211/https://engineering.linkedin.com/blog/2016/10/building-the-linkedin-knowledge-graph|url-status=live}}

This also lets them train machine learning models that can infer new properties about an entity or further information that may apply to it for both summary views and analytics.{{Cite web|title=Machine Learning in LinkedIn Knowledge Graph|url=https://www.linkedin.com/pulse/machine-learning-linkedin-knowledge-graph-qi-he|access-date=July 1, 2020|website=www.linkedin.com|language=en|archive-date=October 8, 2021|archive-url=https://web.archive.org/web/20211008100754/https://www.linkedin.com/pulse/machine-learning-linkedin-knowledge-graph-qi-he|url-status=live}}

In January 2013, LinkedIn dropped support for LinkedIn Answers and cited a new 'focus on development of new and more engaging ways to share and discuss professional topics across LinkedIn' as the reason for the retirement of the feature. The feature had been launched in 2007 and allowed users to post questions to their network and allowed users to rank answers.

In 2014, LinkedIn retired InMaps, a feature which allowed you to visualize your professional network.{{cite web|url=https://techcrunch.com/2014/09/01/linkedin-is-quietly-retiring-network-visualization-tool-inmaps/|title=LinkedIn Is Quietly Retiring Network Visualization Tool InMaps|date=September 2, 2014 |access-date=November 27, 2017|archive-date=November 1, 2017|archive-url=https://web.archive.org/web/20171101154602/https://techcrunch.com/2014/09/01/linkedin-is-quietly-retiring-network-visualization-tool-inmaps/|url-status=live}} The feature had been in use since January 2011.

LinkedIn allows professionals to build exposure for their brand within the site itself and on the World Wide Web as a whole.

LinkedIn also allows users to research companies, non-profit organizations, and governments they may be interested in working for. Typing the name of a company or organization in the search box causes pop-up data about the company or organization to appear. Such data may include the ratio of female to male employees, the percentage of the most common titles/positions held within the company, the location of the company's headquarters and offices, and a list of present and former employees. In July 2011, LinkedIn launched a new feature allowing companies to include an "Apply with LinkedIn" button on job listing pages.Colleen Taylor, GigaOm.

LinkedIn sends "invite emails" to Outlook contacts from its members' email accounts, without obtaining their consent. The "invitations" give the impression that the e-mail holder themself has sent the invitation. If there is no response, the answer will be repeated several times ("You have not yet answered XY's invitation.")

The sign-up process includes users entering their email password (there is an opt-out feature). LinkedIn will then offer to send out contact invitations to all members in that address book or that the user has had email conversations with. When the member's email address book is opened, it is opened with all email addresses selected, and the member is advised invitations will be sent to "selected" email addresses, or to all. LinkedIn was sued for sending out another two follow-up invitations to each contact from members to link to friends who had ignored the initial, authorized invitation.

In November 2014, LinkedIn lost a motion to dismiss the lawsuit, in a ruling that the invitations were advertisements not broadly protected by free speech rights that would otherwise permit use of people's names and images without authorization.[http://betanews.com/2014/06/15/linkedin-to-face-lawsuit-for-spamming-users-email-address-books/ LinkedIn to face lawsuit for spamming users' email address books] {{Webarchive|url=https://web.archive.org/web/20220306035251/https://betanews.com/2014/06/15/linkedin-to-face-lawsuit-for-spamming-users-email-address-books/ |date=March 6, 2022 }}, BetaNews[http://gigaom.com/2013/09/21/linkedin-is-breaking-into-user-emails-spamming-contacts-lawsuit/ LinkedIn is "breaking into" user emails, spamming contacts – lawsuit] {{Webarchive|url=https://web.archive.org/web/20140617102149/http://gigaom.com/2013/09/21/linkedin-is-breaking-into-user-emails-spamming-contacts-lawsuit/ |date=June 17, 2014 }}, Gigaom.com{{cite web|url=http://www.mediapost.com/publications/article/238275/judge-rejects-linkedins-free-speech-argument-in-b.html?|title=Judge Rejects LinkedIn's Free-Speech Argument In Battle Over Email Invitations|website=Mediapost.com|access-date=July 3, 2015|archive-date=July 4, 2015|archive-url=https://web.archive.org/web/20150704024121/http://www.mediapost.com/publications/article/238275/judge-rejects-linkedins-free-speech-argument-in-b.html|url-status=live}} The lawsuit was eventually settled in 2015 in favor of LinkedIn members.

In June 2012, cryptographic hashes of approximately 6.4 million LinkedIn user passwords were stolen by Yevgeniy Nikulin and other hackers who then published the stolen hashes online.{{cite web|url=http://www.pcworld.com/article/257045/update_linkedin_confirms_account_passwords_hacked.html|title=LinkedIn Confirms Account Passwords Hacked|date=June 6, 2012|publisher=PC World.com|access-date=June 6, 2012|archive-date=September 14, 2012|archive-url=https://web.archive.org/web/20120914074910/http://www.pcworld.com/article/257045/update_linkedin_confirms_account_passwords_hacked.html|url-status=dead}} This action is known as the 2012 LinkedIn hack. In response to the incident, LinkedIn asked its users to change their passwords. Security experts criticized LinkedIn for not salting their password file and for using a single iteration of SHA-1.{{cite news|author=Finkle, Jim and Jennifer Saba|url=https://www.reuters.com/article/linkedin-breach-idINL1E8H6CBC20120606|title=LinkedIn suffers data breach|date=June 6, 2012|work=Reuters|access-date=June 7, 2012|archive-date=March 15, 2016|archive-url=https://web.archive.org/web/20160315014435/http://www.reuters.com/article/linkedin-breach-idINL1E8H6CBC20120606|url-status=live}} On May 31, 2013, LinkedIn added two-factor authentication, an important security enhancement for preventing hackers from gaining access to accounts.{{cite web|url=http://lifehacker.com/linkedin-just-added-two-factor-authentication-so-enabl-510680312|title=LinkedIn Just Added Two-Factor Authentication, So Enable It Now|date=May 31, 2013|publisher=Lifehacker.com|access-date=October 6, 2015|archive-date=October 6, 2015|archive-url=https://web.archive.org/web/20151006222441/http://lifehacker.com/linkedin-just-added-two-factor-authentication-so-enabl-510680312|url-status=live}} In May 2016, 117 million LinkedIn usernames and passwords were offered for sale online for the equivalent of $2,200 (~${{Format price|{{Inflation|index=US|value=2200|start_year=2016}}}} in {{Inflation/year|US}}).{{cite web|url=http://mashable.com/2016/05/18/linkedin-hack//|title=LinkedIn resetting passwords after 117 million user credentials stolen|date=May 19, 2016|publisher=MashableUK|access-date=May 19, 2016|archive-date=March 6, 2022|archive-url=https://web.archive.org/web/20220306035304/https://mashable.com/article/linkedin-hack|url-status=live}} These account details are believed to be sourced from the original 2012 LinkedIn hack, in which the number of user IDs stolen had been underestimated.

In 2010, Social Science Computer Review published research by economists Ralf Caers and Vanessa Castelyns who sent an online questionnaire to 398 and 353 LinkedIn and Facebook users respectively in Belgium and found that both sites had become tools for recruiting job applicants for professional occupations as well as additional information about applicants, and that it was being used by recruiters to decide which applicants would receive interviews.{{cite journal|last1=Caers|first1=Ralf|last2=Castelyns|first2=Vanessa|title=LinkedIn and Facebook in Belgium: The Influences and Biases of Social Network Sites in Recruitment and Selection Procedures|year=2011|journal=Social Science Computer Review|publisher=SAGE Publications|volume=29|issue=4|pages=437–448|doi=10.1177/0894439310386567|s2cid=60557417|url=https://www.researchgate.net/publication/258190136|access-date=September 15, 2020|archive-date=March 6, 2022|archive-url=https://web.archive.org/web/20220306035250/https://www.researchgate.net/publication/258190136_LinkedIn_and_Facebook_in_Belgium_The_Influences_and_Biases_of_Social_Network_Sites_in_Recruitment_and_Selection_Procedures|url-status=live}} In May 2017, Research Policy published an analysis of PhD holders use of LinkedIn and found that PhD holders who move into industry were more likely to have LinkedIn accounts and to have larger networks of LinkedIn connections, were more likely to use LinkedIn if they had co-authors abroad, and to have wider networks if they moved abroad after obtaining their PhD.{{cite journal|last1=Baruffaldi|first1=Stefano H.|last2=Di Maio|first2=Giorgio|last3=Landoni|first3=Paolo|title=Determinants of PhD holders' use of social networking sites: An analysis based on LinkedIn|year=2017|journal=Research Policy|publisher=Elsevier|volume=46|issue=4|pages=740–750|doi=10.1016/j.respol.2017.01.014|url=https://www.sciencedirect.com/science/article/abs/pii/S0048733317300239|access-date=September 11, 2020|archive-date=June 12, 2020|archive-url=https://web.archive.org/web/20200612123935/https://www.sciencedirect.com/science/article/abs/pii/S0048733317300239|url-status=live}}

Also in 2017, sociologist Ofer Sharone conducted interviews with unemployed workers to research the effects of LinkedIn and Facebook as labor market intermediaries and found that social networking services (SNS) have had a filtration effect that has little to do with evaluations of merit, and that the SNS filtration effect has exerted new pressures on workers to manage their careers to conform to the logic of the SNS filtration effect.{{cite book|last=Sharone|first=Ofer|editor-first=Steven|editor-last=Vallas|title=Emerging Conceptions of Work, Management and the Labor Market|chapter=LinkedIn or LinkedOut?

Rhee, Hwang, and Tan further found that referring employees in higher hierarchical positions than the job candidates were more likely to provide referrals and that gender homophily did not reduce the competition self-protection effect.{{cite SSRN |last1=Rhee|first1=Melissa|last2=Hwang|first2=Elina|last3=Tan|first3=Yong|title=Social Hiring: The Right LinkedIn Connection that Helps You Land a Job|year=2018|ssrn=3261180}}

In July 2019, sociologists Steve McDonald, Amanda K. Damarin, Jenelle Lawhorne, and Annika Wilcox performed qualitative interviews with 61 human resources recruiters in two metropolitan areas in the Southern United States and found that recruiters filling low- and general-skilled positions typically posted advertisements on online job boards while recruiters filling high-skilled or supervisor positions targeted passive candidates on LinkedIn (i.e. employed workers not actively seeking work but possibly willing to change positions), and concluded that this is resulting in a bifurcated winner-takes-all job market with recruiters focusing their efforts on poaching already employed high-skilled workers while active job seekers are relegated to hyper-competitive online job boards.{{cite book|last1=McDonald|first1=Steve|last2=Damarin|first2=Amanda K.|last3=Lawhorne|first3=Jenelle|last4=Wilcox|first4=Annika|editor-last1=Vallas|editor-first1=Steven|editor-last2=Kovalainen|editor-first2=Anne|title=Work and Labor in the Digital Age|series=Research in the Sociology of Work|chapter=Black Holes and Purple Squirrels: A Tale of Two Online Labor Markets|year=2019|place=Bingley, UK|publisher=Emerald Publishing Ltd|volume=33|pages=93–120|isbn=978-1789735864|doi=10.1108/S0277-283320190000033006|s2cid=197889035|url=https://www.emerald.com/insight/content/doi/10.1108/S0277-283320190000033006/full/html|access-date=September 15, 2020|archive-date=August 10, 2020|archive-url=https://web.archive.org/web/20200810190926/https://www.emerald.com/insight/content/doi/10.1108/S0277-283320190000033006/full/html|url-status=live}} In December 2001, the ACM SIGGROUP Bulletin published a study on the use of mobile phones by blue-collar workers that noted that research about tools for blue-collar workers to find work in the digital age was strangely absent and expressed concern that the absence of such research could lead to technology design choices that would concentrate greater power in the hands of managers rather than workers.{{cite journal|last1=Brodie|first1=Jacqueline|last2=Perry|first2=Mark|year=2001|title=Designing for mobility, collaboration and information use by blue-collar workers|journal=ACM SIGGROUP Bulletin|publisher=Association for Computing Machinery|volume=22|issue=3|pages=22–27|doi=10.1145/567352.567356|s2cid=42218697 }}{{cite news|last=Picciotto|first=Rebecca|date=April 20, 2023|title=Blue-collar job openings have 'gone gangbusters'—workers aren't finding them on LinkedIn|publisher=CNBC|url=https://www.cnbc.com/2023/04/20/blue-collar-jobs-linkedin-online-platforms.html|access-date=May 1, 2023|archive-date=April 30, 2023|archive-url=https://web.archive.org/web/20230430180121/https://www.cnbc.com/2023/04/20/blue-collar-jobs-linkedin-online-platforms.html|url-status=live}}

In a September 2019 working paper, economists Laurel Wheeler, Robert Garlick, and RTI International scholars Eric Johnson, Patrick Shaw, and Marissa Gargano ran a randomized evaluation of training job seekers in South Africa to use LinkedIn as part of job readiness programs. The evaluation found that the training increased the job seekers employment by approximately 10 percent by reducing information frictions between job seekers and prospective employers, that the training had this effect for approximately 12 months, and that while the training may also have facilitated referrals, it did not reduce job search costs and the jobs for the treatment and control groups in the evaluation had equal probabilities of retention, promotion, and obtaining a permanent contract.{{cite report|last1=Wheeler|first1=Laurel|last2=Garlick|first2=Robert|last3=Johnson|first3=Eric|last4=Shaw|first4=Patrick|last5=Gargano|first5=Marissa|title=LinkedIn(to) Job Opportunities: Experimental Evidence from Job Readiness Training|year=2019|work=Economic Research Initiatives at Duke|publisher=Duke University|ssrn=3452609|doi=10.2139/ssrn.3452249|s2cid=203525431|url=https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3452249|access-date=September 14, 2020|archive-date=October 30, 2020|archive-url=https://web.archive.org/web/20201030031827/https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3452249|url-status=live}} In 2020, Applied Economics published research by economists Steffen Brenner, Sezen Aksin Sivrikaya, and Joachim Schwalbach using LinkedIn demonstrating that high status individuals self-select into professional networking services rather than workers unsatisfied with their career status adversely selecting into the services to receive networking benefits.{{cite journal|last1=Brenner|first1=Steffen|last2=Sivrikaya|first2=Sezen Aksin|last3=Schwalbach|first3=Joachim|title=Who is on LinkedIn?

It was speculated to have been blocked because it is an easy way for dissidents to access Twitter, which had been blocked previously.{{cite news |last=Ungerleider |first=Neal |title=China blocks access to LinkedIn |url=http://www.cnn.com/2011/TECH/social.media/02/25/china.blocks.linkedin.fastco/index.html?iref=NS1 |access-date=February 25, 2011 |newspaper=Fast Company |date=February 25, 2011 |archive-date=June 28, 2011 |archive-url=https://web.archive.org/web/20110628234633/http://www.cnn.com/2011/TECH/social.media/02/25/china.blocks.linkedin.fastco/index.html?iref=NS1 |url-status=live }} After a day of being blocked, LinkedIn access was restored in China.{{cite news |url=https://www.reuters.com/article/us-linkedin-idUSTRE71O5VY20110225 |last=Baker |first=Liana |title=LinkedIn website working again in China |date=February 25, 2011 |newspaper=Reuters |access-date=July 5, 2021 |archive-date=October 8, 2021 |archive-url=https://web.archive.org/web/20211008113016/https://www.reuters.com/article/us-linkedin-idUSTRE71O5VY20110225 |url-status=live }}

In 2016, a Moscow court ruled that LinkedIn must be blocked in Russia for violating a data retention law which requires the user data of Russian citizens to be stored on servers within the country. The relevant law had been in force there since 2014.{{cite news |date=November 17, 2016 |title=Russland blockiert LinkedIn |language=de |newspaper=Spiegel Online |url=http://www.spiegel.de/karriere/linkedin-wird-in-russland-gesperrt-a-1121723.html |url-status=live |access-date=March 3, 2018 |archive-url=https://web.archive.org/web/20220306035257/https://www.spiegel.de/karriere/linkedin-wird-in-russland-gesperrt-a-1121723.html |archive-date=March 6, 2022}}{{cite web |last=Wilkens |first=Andreas |date=November 17, 2016 |title=Russland blockiert Linkedin |url=http://www.heise.de/newsticker/meldung/Russland-blockiert-Linkedin-3490326.html |url-status=live |archive-url=https://web.archive.org/web/20180222043741/https://www.heise.de/newsticker/meldung/Russland-blockiert-Linkedin-3490326.html |archive-date=February 22, 2018 |access-date=March 3, 2018 |website=heise.de |language=de}} This ban was upheld on November 10, 2016, and all Russian ISPs began blocking LinkedIn thereafter.

In October 2021, after reports of several academicians and reporters who received notifications regarding their profiles will be blocked in China, Microsoft confirmed that LinkedIn will be shutting down in China and replaced with InJobs, a China exclusive app, citing difficulties in operating environments and increasing compliance requirements.{{cite news

Since 2010, LinkedIn has contributed several internal technologies, tools, and software products to the open source domain.{{cite news |last1=Asay |first1=Matt |title=The secrets to LinkedIn's open source success |url=https://www.infoworld.com/article/3058778/the-secrets-to-linkedins-open-source-success.html |work=InfoWorld |date=20 April 2016 |language=en |access-date=July 14, 2021 |archive-date=July 15, 2021 |archive-url=https://web.archive.org/web/20210715000014/https://www.infoworld.com/article/3058778/the-secrets-to-linkedins-open-source-success.html |url-status=live }} Notable among these projects is Apache Kafka, which was built and open sourced at LinkedIn in 2011.{{cite news |last1=Levy |first1=Ari |title=Confluent climbs 25% in Nasdaq debut after cloud software developer raises over $800 million in IPO |url=https://www.cnbc.com/2021/06/24/confluent-climbs-26percent-after-raising-828-million-in-ipo.html |work=CNBC |date=24 June 2021 |language=en |access-date=July 14, 2021 |archive-date=July 15, 2021 |archive-url=https://web.archive.org/web/20210715000002/https://www.cnbc.com/2021/06/24/confluent-climbs-26percent-after-raising-828-million-in-ipo.html |url-status=live }}

In Proceedings of the 2013 ACM SIGMOD International Conference on Management of Data (pp. 1125-1134). ACM. For example, this data can help to shape patterns of deception in resumes. Findings suggested that people commonly lie about their hobbies rather than their work experience on online resumes.Guillory, J., & Hancock, J. T. (2012).
