Narrative: Please note: My area has filed dozens; possibly even over 100 [safety reports] against this aircraft/parachute jump school and nothing has been done since.I was working a very busy combined sector and a parachute jump plane checks onto the sector like he normally does and advises he's going VFR/13500 feet to release parachute jumpers on a VERY busy ZZZ Arrival line. We had aircraft all lined up 15 Miles in trail for at least 175 miles and I told the aircraft for traffic to maintain VFR/9500 feet or below for the jump. The pilot responded and said 'NO. I am going to 13500 feet and releasing jumpers.' For collision and safety of other aircraft; I told him that jumpers are not authorized at that altitude. In the past; he has released jumpers with no prior warning right in the face of ZZZ regional jet arrivals and commercial aircraft have asked why there are bodies so close to their aircraft. He said he wanted to then terminate his radar service do jumps without talking to ATC. For safety reasons; I kept him on my frequency.I told the pilot multiple times; that jumpers are not authorized at his altitude due to a safety concern and he refused to comply. I started to vector ZZZ arrivals around UNAUTHORIZED PARACHUTE JUMPING to keep everyone safe. THE VFR Parachute jump plane then started arguing with me about FAR's over the frequency and started challenging me by letting me know when the jumpers are going to be released. Once again; I told him; that parachute jumping is not being authorized at this time at his altitude. I told him to call ZNY for a possible pilot deviation.Due to the IMMEDIATE THREAT of ZZZ arrivals entering New York airspace. I am requesting the jump school be temporary shut down and the pilot license be revoked until an investigation can occur.


Second narrative: We have an aircraft; whose call sign frequently changes; but is known as [Company call sign]. He does jumper activities in the vicinity of ZZZZZZ intersection. He checked on climbing VFR to 13500 feet and I told him where in minutes my next 2 ZZZ inbound aircraft were. The first was about 4 min away and the second was 12. I told him; that after the 2nd aircraft; I had more aircraft close behind. He proceeded to make a very slow climb. He reached altitude when the 2nd aircraft was 4 min from ZZZZZ intersection and told me he would like to let the jumpers go in 2 minutes. I told him I was unable due to the inbound ZZZ and that I had another 2 aircraft behind him. He says ok. About 2 min pass and he asks where the ZZZ aircraft is. I tell him about 2 min from ZZZZZ intersection; he asks where the one behind him is. I say about 5 min from ZZZZZ intersection. He tells me he will jump after the 2 min away aircraft passes. I call traffic; he asks me again a minute later where he is. I tell him and he gets the aircraft in sight. I ask if he will be able to jump in one minute; he says 'confirm.' I coordinated the time with approach and then I called [sector] to point out an aircraft; since his descent would be held up for the Aircraft Y. Aircraft X inquires if he should expect ZZZZZ intersection at 10000 feet. I tell him no; that I'm holding him up for Aircraft Y. Aircraft X remarks that this is not a good area for jumper operations. I wait 2 min and ask the Aircraft Y what his status is. He says something like 'were coming down.' I take that to mean; he has dropped; since he should have already released his jumpers; and that he is starting his descent. I don't observe him descending; so I ask if he is descending or staying at 13500 feet. He says he staying at 13500 feet. I tell him that he should have told me that; since I was holding up my aircraft. I turn to Aircraft X and tell him to descend and be level in 2 min or less. Aircraft X is over ZZZZZ intersection; Aircraft Y is over him at ZZZZZ intersection at 13500 feet and announces that he dropped the jumpers and would like to begin descent. I was surprised and asked if he just dropped them; since he was supposed to have done so minutes ago. He says he did and wants to start his descent. I tell him that he can't because he's still over the Aircraft X. I switch Aircraft X to approach and he tells me that the jumpers were dropped close to him and that it was unsafe. I tell him that he should file a report; and he said that he would. Aircraft Y once again asks me to start his descent and I say he is now clear of Aircraft X and he can descend. This is a recurring issue with this jumper aircraft. He frequently does not listen to ATC instructions; is misleading and difficult to work with. We could either change the ZZZ arrival to go over ZZZ VOR and that would keep them away from the jump site or we have to put restrictions in for this jumper. I don't think it is a safe site for the jumping at all; but if it is to continue; he needs to be made to follow our instructions and to be clear and accurate in his expression on what his intentions are and how long it will take for him to accomplish his tasks. Telling me that he can do the jumps in 1 minute and then releasing them 3 or 4 mins later; is not only misleading; it is dangerous. The pilot of the arriving aircraft called after landing and said he saw the jumpers about 400ft from his aircraft. This is dangerous to not only the jet aircraft; carrying 100's of passengers; but the jumpers themselves; who have no idea the dangerous situation the pilot is putting them in. Actions need to be taken before something traumatic and irreversible happens.


Synopsis: ZNY Center Controller reported of a skydiving aircraft that ignored ATC instructions; argued with controllers on frequency; and gave misleading information to have his requests approved.
