Why not implement a moderation ala digg / slashdot.  This way, Charles won't have to watch the forums like a hawk with his finger constantly pounding on the lifetime ban button.  Yea, it's not perfect, but it'll allow all of us to filter out the noise.

People constatnly modded at trolls get no modpoints (and their posts show collapsed) and people modded up get more modpoints.  Either that or ignore lists.

Just a thought...
