Soon you'll need a way to authenticate NFTs (prove that the one you're bidding on was minted by the advertised artist), and then you'll immediately lose the proposed benefits of NFTs -- decentralization and anonymous trust.
If you ask “well, how do you know that’s their real deviant profile?”, at that point, it’s not a crypto/NFT problem, but an identity problem. My understanding is that keybase.io was one way to do that, but I never used it so I can’t say much. What if a scammer registered the keybase first before the real artist? Not sure what happens in that case.
What about keybase? Have people figured this out in a decentralized way?
