:{{BotTrialComplete}}. I kept a log here, however I'm not 100% confident that has everything. There are 4 bluelinks on that page, 3 of which were vandalism, and 1 was a misspelling. LegoK^ontribsT^alkM 17:39, 19 September 2012 (UTC)

::This is precisely what I was hoping to see when I requested this bot — it both succeeds in having useless redirects deleted and in having damaged-but-useful redirects sent back to being useful. Nyttend (talk) 02:41, 20 September 2012 (UTC)

::Do you want another trial or are you confident you've fixed everything? MBisanz ^talk 13:46, 21 September 2012 (UTC)

:::I'm not sure those are bugs though. The bot currently can't detect anything except whether the redirect is broken or not. I could add in something that would check if the page had content before it was redirected, but I'm not sure what the bot would do after that? Revert? Tag with something else? Personally I think that being tagged for CSD (while erroneous) gets attention faster for a human to look at it, than it would if just left alone. As for the misspelling, since that was the original edit to the page, I don't think there is anyway the bot could have caught that. LegoK^ontribsT^alkM 21:33, 21 September 2012 (UTC)

::::Those aren't bugs. Many redirects with old histories should be deleted, and all of them qualify for speedy deletion regardless of what should be done with them. The bot's using a speedy deletion template with a big warning to admins to check for possible targets before deleting; it really can't know what to do, and by bringing these redirects to administrative attention, the bot is taking care of them quite well.
