Yes, I noticed the newest member is Snuperr and his site is a drug site. Clearly an adbot. The best thing for that is just for Ville to ban them as he sees them. It's a problem unfortunately that all forums have to deal with and there is no easy solution.
I've looked at the memberlist, and curiously enough virtually every member joined from September 18th and onward is an adbot. I'm sure there are similar streaks earlier on. They're quite obvious as they have 0 posts in most cases. This is quite gratuitous however, cause that means we've got well over 20 adbots.
