Now you see it; now ya don't!
I would like to leave one of the 'spam' posts up sometime (buy cheap drugs here type) and ask about ten thousand of you guys to reply with huge files and bomb their mailbox but you might be affraid it would put you on their list. We get them every day and usually remove the post and the new user. I have now removed one of the jerks post but, changed his password and neglected to tell him what the new one is. At least he won't come back in with that name and email address.
