I am a Moderator on another BBS and we too have the same spammers over there as you do here..we send our spam to what we call the "Dungeon"..it sits there till the admin folks and look thru it and ban the account/username..the dungeon is only visable to the "sysops", not to the general population..we probably have 10 moderators on that bbs and between all of us, spam is hardly ever seen by any of our users, it is policed very well.
