OK - here is what I propose.
How about a rule that allows for an infraction for "trolling"?
That would include posts and threads that are intended to be inflammatory or flame bait.
Having said this though, it would apply to everyone. Not certain members only. Plus, I would highly recommend adding a "Flame Thrower" forum that would allow for purely flame bait threads.
What say ye? I can't promise that it will be so, mongo is only pawn in game of life.
