I think it's a little unfair to include John Cleese in the list, as his stunt to sell an NFT of a bridge was obviously a satire of the scammy nature of NFTs. As if to say, "if you think NFTs have any value, I've got a bridge to sell you".
By that reasoning the author of "promotingthegrift.com" also belongs on the list—unless you don't think making the front page of HN is enough to qualify you as a "celebrity"?
Um, did it sell?
