Hi Sherif: I like the idea of flagging a comment. Voting down can take too long to produce results. Particularly if a lousy note is way down on the bottom (chronologically or vote wise) of a page with a lot of comments, so few people get that far to add their additional down vote.
I haven't looked at your UI, but someone mentioned it being complicated. It seems all that's needed is an input box for peple to explain why the item is problematic.
