As long as you are keeping track of people (which isn't always a bad thing) you may as well say 'moderators can post on articles that they moderate as long as their average score is above X' That way moderators who post good comments, and moderate are allowed to do both, and those who do it, and get moderated down to a low score for posting stupid comments can't. You figure you've already got the data,just give it a whack, play with the threshold and see if it works.
