They could approach the intermediate services that are usually used to access the blockchain. Moxie had his NFT removed by one of the market places and gone it was from the wallet, gone for all practical purposes.
I'd avoided looking into NFT's because the concept strikes me as being just, well, cringe, but I'd assumed at least that the chains stored the hash of a jpeg or something.
You're telling me that they're not even immutable? They really just store urls with _no checksum of what's on the other end of the url_!?

If people were pumping and dumping physical goods, using shill bidding and other tactics blatantly on display in NFTs, they'd go to prison.
The hammer is gonna fall hard on lots of shady characters in the nft space, and a whole bunch of famous people will get spanked or look really stupid when law enforcement catches up.
