Wow, two in a week. :/ Taken care of now.
Matt: thanks for the suggestion, but the total level of spam here isn't that bad yet; other than just now, I don't think we've had more than one spammer per month actually posting, and it's all human-originated, which means that anything mollom would be unsure about would sail right through.
Mostly we're 'suffering' from profile link spam registrations for the benefit of google (~10 per week), but I'm deleting those links almost as fast as they're put in, and registrations for that purpose are slowly but steadily declining. I still have a couple of tricks up my sleeve which just take time to implement (as would putting in something like mollom), and the volume has remained low enough that finding that time hasn't become a priority yet. (2 minutes per day is easier to justify than one solid block of 2 hours, even if it'd pay itself back swiftly enough.) :)
