The spammers have just found my ikiwiki.  I have my main pages locked but allow open changes to my discussion pages and in the last few days one page in particular has been overwritten by spam about nine times, each edit was from a different IP address.
http://adam.shand.net/iki/recentchanges/ (sorry for the funny formatting, I upgraded to the latest version and haven't tracked down what changed yet)
I'll probably lock down my discussion pages to require a login of some sort and hopefully that will slow them down.  Is anyone else seeing problems on their wiki?
As far as techniques for reducing spam I've found the MoinMoin technique of refusing to allow page saves with known spam URLs combined with a group maintained list of URLs to be fairly effective.

I have yet to hear of any spammer using openid.. --[[Joey]]


Mh.. well. I know this problem, too. I leave the Discussion sites open for no registrations, so that visitors can easily write a comment to this specific blog entry without the need for registration. (This would be the same behaviour, as many blogging engines are using). Maybe it is possible to wrote a plugin that would scan the text which is submitted via spamassassin or something similar. (Using this combined with known spam URLs would maybe reduce the load of the server if there are many webpages which are getting editted by someone). If you like this idea Joey I might be interested to write such a plugin after my exams this and the next month. :) -- [[Winnie]]
