I've written a quick script which does an hourly download from Stopforumspam and automatically blocks the IPs listed in their database.
yeah but the people who are using the spam software are downloading new proxy servers every hour as well, so they are constantly coming up with new IPs.
I don't understand what deleting fluff posts would have to do with stopping spam. None of the blackhat forums I've ever read suggest that spammers make a couple of fluff posts before spamming. If I were a spammer, the last thing I would do is make a fluff post. I would just want to spam you and move on (btw: I am NOT a spammer, in case you are wondering.)
IncrediBill's idea seems pretty good.
