Tough call on heavier filtering. Be a shame to see this place end up like big shots, where hurt feelers for getting called out for talking out your rectum rates a suspension/ban. Besides, the mods/admin here already work way beyond their pay scale.
That said, after this recent debacle, there is definitely a sound case for shifting the line in the sand a smidge. Tough to win a fight when you're morally forced to wear gloves and hit above the belt, against an opponent who doesn't even know what morals are.
