Yeah, only full Admins can, apparently.
Tom installed a spam stopper. It checks names, IPs, and e-mails with a database. The red ones are confirmed on the database to be spammer accounts/IPs/e-mails. The yellow are suspected. Whites have had no reports against them.
As you can see, there are a LOT of spambots in the queue. This will help keep the forums a bit cleaner, fortunately.
Doesn't look like it ran for the accounts waiting for activation, but there are a lot of spam accounts in there too. Can tell just by how they appear (the name and e-mail usually).
