I never had this much spam...ever

Best thing you can do IMO is to install a couple of registration mods to keep the bots from registering. This will cut your spam in a major way. The next thing you can do, is install the mod that doesn't allow a user to post links. I've done this on my forum so that you can't post a link until you have 10 posts. This keeps the human spammers from spamming.
