Hi all My dokuwiki installation <http://resources.phplist.com> has recently been bombarded with bogus registrations. Initially it was one or two a day, but since the 27th of March it started to become quite a few more. In those 8 days I got 1915 signups. That's more than 200 per day. I don't allow editing for anyone, so it is not a danger for filling my wiki with junk, but it's still not great. All of them are completely useless, and now I'm also seeing a lot of bounces from Hotmail and Yahoo where these accounts are requesting their passwords, but the emails are incorrect, so the mail bounces. That's of course terrible for my spam rating for those providers. When I first noticed it I installed the "badbehaviour plugin" that Andreas made, but it didn't really stop the signups. The BB-plugin gives "452 accesses were blocked in the last 7 days." but the above 1915 were not blocked. Now, a year and a half ago I wrote a class for my site <http://www.phplist.com/formspamclass> that uses Mollom, Akismet, Stopforumspam and Honeypot to stop spam signups to my site. That was fairly successful, so I have now wrapped this class in a Dokuwiki plugin and I've installed it on my own Dokuwiki site. It's in early stages, and I need to document it and tidy it up, but you can find it here: https://github.com/phpartisan/dokuwiki-botbouncer At the moment I've implemented it similar to the badbehaviour plugin, and it uses the "action.php" to disallow POST requests. In order to avoid DOSsing the services I only do a check on a POST. But I think it may be more sensible to work on the auth.php instead. Anyway, I'd be interested in comments, and to hear if others have experienced the same, and if so, what they did about it. Michiel
