Persistant and prolific ... spammers

The "newest member" names do NOT reflect whether that person is an actual member with access as yet ... it just reflects the last person the register, who may or may not have been approved by now. If not approved, they have absoloutely NO access to the forum other than like any other "guest" ... in other words, they can NOT log in!!! They just sit there until one of us admins see's them and they are removed and IP's banned etc, or are left to sit forever so they can't use that email address to attempt another registering Master Sunray is the decider in what to do with these ... critters.
