Ah, I think you can write that off -- if you have an open site you're going to
get an occasional spammer.

FWIW, from my experience with the User Wiki, the main thing you need is the
BadContent filter. 99% of all spam is a link to a site and you can at least
prevent second occurrences of a spammer linking to the same site. I currently
have 2500 content regex's protecting the user wiki.

You're bound to have a massive attack at some point and the content filter is
the only thing that will stop it. IP Blacklisting is useless all the spammers
have bot nets now. IP Throttling is pretty much useless too - they use lots of
different machines with different IPs. Plus, they mass spammers know how to
slow down their bot nets to work with the throttling. After 2 hours with 10
machines @ 5 pages/machine they can do alot of damage.
