We had an entirely automated system to temporarily block users who exceeded their bandwidth limit. When that happened we brought down the port on the switch. If they moved to a different port we brought it down as well. If they had changed their MAC they would have to associate it with their username (using our home grown NAC) and then we would block them then. As for support we had standard hours for a helpdesk staffed by students.
