I've just completed the initial version of a "Combating spam" page on
MediaWiki.org, which can be found at
http://www.mediawiki.org/wiki/Manual:Combating_spam. I'm hoping that
with the right incoming links, it will become an introduction to
dealing with the issue for new wiki operators, since anti-spam
measures are one of our more commonly asked questions.
I'm throwing the URL out here both to gather feedback, and to make it
known to the user base at large.
