@Mochii yeah I agree. I think in such cases, the NFT, if it uses copyrighted images would not hold any value. The problem occurs if the issuer sells these NFT to 3rd parties and then disappears.
I remember this situation many years back when I was still a schoolboy. I created a website with silhouette of buildings and tried to sell each building to different people. A few days after launching, I received a cease and desist letter from a lawyer saying that these images are copyrighted material and cannot be used. I immediately took down the website. Had I sold any of these buildings, I probably would have to refund the purchasers. Of course this was in early 2000s before there was any blockchain or NFT for that matter!
If an NFT issuer is using copyrighted material and is still actively selling the NFT, the copyright owner can go after them and ask them to stop. However, if the NFT owner successfully sold everything before the copyright owner realizes it and then disappears, it will be harder to stop.
But there are still legal ways to fix it. The way NFTs are hosted now, the images are usually stored in a centralized server on AWS for example. The token metadata, ERC721 for example only has a link to the image. Meaning if the issuer, removes the image, there goes the NFT image too.
It is theoretically possible to store the images on IPFS for example but it is still challenging and most developers do not take this route. If it’s on IPFS and the NFT issuer has disappeared then it will be a whole different issue.
