[Carnage]

I had about 100 registrations per day until I added an 'are you a spambot' question to the registration form. This cut it down to about 10. From there I've banned a lot of isp's (esp chineese ones) and the spam seems to be down to a more manageable trickle.

To get rid of the rest of the spam, I've been working on a new modification Spam****** (spam censor) which is intended to block spam by the post contents using similar techniques to those spam assasin uses on email spam. Realistically, content based filtering is the best way of dealing with spam, once a forum has configured the filters any post which isn't 'on topic' will get flagged as spam.
