spammer database

[bad_brain]

I found a real nice site for forum owners (or any site that has some kind of registration system):
http://www.stopforumspam.com/search

on the search page you can check if email addresses, domains and IPs belong to known spammers.
the sql file to apply known spammer names/emails to phpbb seems also to be really useful, will check it out on suck-o too...
