Posterous

Posterous allowed posting of content directly to one's blog via e-mail, choosing where to put the content based on the return address of the e-mail. While this feature was very convenient, return e-mail addresses are easily spoofed, allowing for malicious users to post unwanted content on another person's blog.{{cite web|url=http://www.readwriteweb.com/archives/posterous_minimalist_blogging.php |title=Posterous: Minimalist Blogging – ReadWrite |publisher=Readwriteweb.com |access-date=2013-07-17}} Posterous claimed that they could filter out messages not actually sent by the account holder through other means besides the return address.{{cite web |url=http://posterous.com/faq/ |archive-url=https://web.archive.org/web/20080620084737/http://posterous.com/faq |url-status=dead |archive-date=June 20, 2008 |title=Knowledge Base – Posterous Spaces: Share Smarter |publisher=Posterous.com |access-date=2012-08-31}} They did not publish their methods, but it appears that they used a combination of SPF-checking and filters on e-mail headers to verify that the e-mail client or machine from which the e-mails were sent are similar to previously verified e-mails.{{cite web|url=http://news.ycombinator.com/item?id=1441997 |title=How I "hacked" Dustin Curtis's Posterous. | Hacker News |publisher=News.ycombinator.com |access-date=2012-08-31}} Posterous did not offer any options for the user to require confirmation on all posts, no matter who sends them.

In June 2008, a blog post on TechCrunch challenged its readers to try to spoof the author's Posterous blog.{{cite web|url=https://techcrunch.com/2008/06/28/posterous-beats-tumblr-in-simplicity/ |title=Posterous Beats Tumblr In Simplicity |publisher=TechCrunch |date=2008-06-28 |access-date=2012-08-31}} Three posters were successful, out of quite a few attempts,{{cite web|url=http://techcrunch.posterous.com/lots-of-fake-post-attempts-onl |archive-url=https://web.archive.org/web/20080701074451/http://techcrunch.posterous.com/lots-of-fake-post-attempts-onl |url-status=dead |archive-date=July 1, 2008 |title=lots of fake post attempts, only three got through - Michael's posterous |publisher=Techcrunch.posterous.com |access-date=2012-08-31}} but Posterous quickly fixed the security hole which allowed these posts to go through.{{cite web|last=Tan |first=Garry |url=http://blog.posterous.com/posterous-has-been-techcrunche |archive-url=https://web.archive.org/web/20080701123428/http://blog.posterous.com/posterous-has-been-techcrunche |url-status=dead |archive-date=July 1, 2008 |title=Posterous has been Techcrunched! - The Official Posterous Space |publisher=Blog.posterous.com |date=2008-06-28 |access-date=2012-08-31}}

In August 2009, Posterous launched PicPosterous, an iPhone application for quickly posting photos to a posterous page.{{cite web|url=http://mashable.com/2009/08/20/picposterous/|title=Posterous for iPhone: Instant Photo and Video Blogging|date=2009-08-20|author=Jennifer Van Grove}}

In January 2011, Posterous launched an app for the Android platform which was supported by 9 different phone models.{{cite web|url=http://posterous.com/mobile/android |title=Mobile |publisher=Posterous |access-date=2012-08-31}}

Posterous agreed to be shut down on March 12, 2012, after it was announced that much of the team was acquired by Twitter.{{cite web|url=http://blog.posterous.com/big-news |title=Posterous is Joining the Flock at Twitter |publisher=Blog.posterous.com |access-date=2013-07-17 |url-status=dead |archive-url=https://web.archive.org/web/20130424063619/http://blog.posterous.com/big-news |archive-date=April 24, 2013 }}

On February 15, 2013, Posterous announced that they would be shutting down the service on April 30, 2013.{{cite web|url=https://news.arihantwebtech.com/posterous-last-post-shut-down/ |title=Posterous: Last Announced by Sachin Agarwal |publisher=News Arihant Webtech}} Users would be able to back up and export their contents to other blogging platforms. Following the shutdown, Posterous URLs displayed a "bye" page showing an image of an astronaut with a spanner and a satellite.{{cite web|title=Posterous FAQ for backup before shutdown |url=http://posterous.com/faq |access-date=May 15, 2016 |url-status=dead |archive-url=https://web.archive.org/web/20131031180410/http://www.posterous.com//faq |archive-date=October 31, 2013 }} As of May 2013, Posterous founders were developing a similar but paid service called Posthaven. Until the Posterous API was shut down, Posterous users could export their data to their new Posthaven account. Posthaven pledged that they would never be acquired and were not looking for any investors.{{cite web|url=https://techcrunch.com/2013/02/15/posterous-will-shut-down-on-april-30th-co-founder-garry-tan-launches-posthaven-to-save-your-sites/ |title=Posterous Will Shut Down On April 30th, Co-Founder Garry Tan Launches Posthaven To Save Your Sites |publisher=TechCrunch |date=2013-02-15 |access-date=2013-07-17}}
