Marc, There is a strategy loosely referred to as "choose your battles well" :-) Let the others bother with their own problems. If you can, hack the server and dump the 500GB - you'll be using resources transferring the 500GB as the other server receives it. Two servers wasting resources because you think you are punishing an offender!
