Cutting off a client who has left box on a pay channel after certain amount of time?

ok say i have a user that has left their box on sly sports 1 and then gone out etc, is it possible to cut the user off until the next channel hop after say 3 hours (more than enough for footie match or movie)? just thinking it would be a handy option to keep peers down? running Oscam on debian server.

Thanks for that Ten , will give him a mail as for what im getting back its not really worth it!
