Why not do something quite simple. Have it setup so that if a user has over a certain karma threshold they can flag a user's post in some manner as being mean-spirited or other such. If a certain number of users also flag the comment, then the poster does not get any of the karma points their comment may have earned. Alternately, the commenting flagging could be coupled with a slashdot style moderation and meta-moderation system.
Already implemented, but "hidden":
you must be on the link to that comment to see the flag link - eg. to see it on pg's GP comment:
