I'm throwing the URL out here both to gather feedback, and to make it known to the user base at large.
What about the use of "noindex" to prevent the indexing of old versions of pages? I read about this on (a somewhat out-of-date) chongqed.org page, but I don't think I understand it fully. There is also a reference to using robots.txt to prevent this, but that's even less clear (links on the page appear to be broken).
If we zap a page that's been spammed and the search engines still find it, the spammers can find your wiki as one with old spam and will re-spam.
Apparently, they can use the "recent changes" pages too. I find that the search engines are frequently accessing recent changes, but I'm not sure how to stop that.
