It seems like a bad idea. Those things could act like a stigma, and we don't need more of those on this forum. Anybody who's boxed in can say "Oh yeah? Well how can I trust you? You have so-and-so infractions! You act immature!"

That and people will be forced, with their shame out in the open, to complain and argue with the admins even more to keep those points from adding up. It might give you more of a hassle.
