Getting OT, but I doubt that a Bayesian filtering method would work on a
Wiki. I wrote about this once:

I'm glad you're warming up to the idea of the MultimediaWiki (or are you?).
Another good counterspam measure would be to have a delay period between
when a user registers and can first post. Most of the spam (and, much
worse, out and out vandalism) we have seen so far is clearly of an
automated nature. Throwing in a delay between reg. and posting will
probably encourage them to move on to a simpler target.
I hear that there are plugins to do this. I just need a spare afternoon
to investigate it.
