You may be right about the paid part, K. I do agree, they must be countered on the public board. My logic on blocking PM's is simply their inability to get a response to the vile things they say privately that would not survive on the public board, even LieHub.

Another tactic is report them for any/all posting violations, legit or not and drive the Mods/Admins crazy. The only issue there is when they're one and the same, it's usually pointless. But increasing their chores a bit can be some relief for us good guys.
