As I feared. This would turn into another automated system that didn't do a good job keeping things civil. It takes effort to have good comments, and while civility flags could be a way of filtering down that work, in the end, it should require a human to actually remove a comment. Maybe hide the comment but make it revealable if it fails the automatic check? You know, link the original comment Ariesmale made behind the <this comment did not meet civility standards>, with a further "click this link at your own risk."
