i see, is true,
i just used the example as it is on Opensea, where the visibility of the link is only open once you own the NFT, the link as i have saw is not connected to the NFT so yes is visible, but is hard to find what is the NFT that points to the link. Also in opensea this has been a feature since i remember so probably must have been working smooth for artist an collectors. I just find it as a cool way to give additional value to any art
