If at all possible, why not simply change the color of a poster's handle from the current Blue ala jimpeel to a lovely shade of Red when they are in peril of being expelled from the board for misconduct.

The next step would be the simple disappearance of the poster from the board and all of their posts becoming the one word BANNED.
