Fighting spam in MediaWiki

Cleaning up spam on and on have resulted in a little tutorial and a presentation I want to show.

Ok, so here is some advice that can alone improve your spam situation.

  1. Healthy community. If your wiki has enough users who care about the content, they will clean up the spam manually.
  2. Heuristics and little tricks. For example you can set the waiting period for all the newly-registered users. That will help because the majority of bots register and immediately write something
  3. Questy captcha instead of any other captcha
  4. If nothing helps use behavior analysis tool called AbuseFilter
