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 I read about this on (a somewhat out-of-date)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.
