Narrative:

Aircraft X is a jump plane that operates at area X. They operate there knowing it is a bad location and does not want to sign an LOA with us because 'no matter what we have to provide services'. Area X is under multiple routes that IFR aircraft have to use to go enroute or just to land at cos. Also area X is in the middle of a practice area that all VFR aircraft want to operate in. In this particular situation aircraft Y was in the way of the descent of aircraft X. The controller issued traffic to both; but both did not get each other in sight. So the controller stopped the descent of the aircraft X. The response is 'blocked' try again 'blocked.' these are not one time offenses. This pilot always does this. Either blatantly ignores instructions or casually say blocked to pretend that they didn't hear it. I've recommended that they hold jumpers because they have jets underneath them. Their response is 'we are jumping in 1 minute'. What do I do? Kill myself trying to move everyone out of the way for them? Putting all the other aircraft in dangerous situations or proximity because they don't want to wait 2 minutes to let the aircraft pass? Luckily yelling on frequency and being unprofessional seemed to stop them. But of course that opens me up to other problems. Get NTSB on it; or something. We can't change the airspace because of one aircraft. I know parachute operations is a big topic; but there has to be some sort of control before it becomes a tombstone policy.
