> An NFT is like a piece of paper titled with the name of the artwork and signed by the artist.

I know nothing about NFTs, but in the last few days I’ve seen a few people turn their Twitter accounts private where they previously posted their artworks. Supposedly to prevent sales of NFTs of their art without their approval. No idea if that’s a real issue or not. However there is another comment here saying they sold a NFT of Mona Lisa. It seems that a “piece of paper with a, possibly forged, signature” might be a better comparison.
