- I also suggest turning onConfirmEdit (it comes with Mediawiki 1.18). We enabled that on our wiki with the QuestyCaptcha module and that dramatically reduced the recent spam. The simpler pattern-based CAPTCHAs have apparently been broken by the spam bots. ConfirmEdit can be configured such that users with some history of edits are no longer required to go through the CAPTCHA test. --JeffLane 19:50, 18 April 2012 (BST)
I turned on email confirmation at sign up for edit rights which looks like it might be doing the trick, there have been a couple of obvious spambot users register since then but no actual posts so fingers crossed ...
