I think every node should have a category in addition to xp: useful, humorous, troll
Registered users would vote on the node category (anonymous monks would have no say). The current majority vote category would be displayed next to the node title (maybe in different colours and/or with a vote count). Penance monk nodes would automatically start life as a single vote for 'troll'. Regular monks can vote their own node 'humorous' to set the tone, otherwise, monks can't vote their own node category. Note the category would continue to change and evolve as more users see fit to vote. The category (and voting it) would be in no way related to xp. The category could be a filter option in Super Search and a personal view filter option for monks.
A 'troll' rating may be the badge of honor a troll is looking for, but once labeled I'm not inclined to follow the rabbit down the hole. Therefore I think that labeling trolls does more over all good than harm.
