So we're suggesting a sub-basement, a lower level even than the CH? And then invite the world in? That would be a neighborhood I wouldn't want to visit after dark.
I still like the distributed moderation solution. Let anybody with more than, say, 17,815 posts move a thread to the sub-basement dungeon. If any such users proved themselves unworthy of that power, such as dumping anything they considered "unfunny" down there, their post counts could be zeroed out in retaliation.
