Freeze them, kill them, unsync them and mute them. There are some very reliable things which you can use to kill the hackers motivation. Just prevent interacting them with the server in any way, and they will loose interest. If you ban them or use any other not 100% sure method like macs, serials, etc, they will only be motivated to hack these things, as all of them can be faked in some way.
