The recent implementation of a -5 karma penalty for replying to comments that are at -3 or below has clearly met with some disagreement and controversy. See http://lesswrong.com/r/discussion/lw/eb9/meta_karma_for_last_30_days/7aon .

Be sure to distinguish between the controversy surrounding Eliezer's provocative comments and the policy as he declares he wishes it and actual disagreement with the implementation as it currently stands. I, for example, are tentatively in favor of the current implementation---but not in favour of the policy as he intends it to be implemented.
