To restate what the twitter user was saying: "It seemed like this was a get-rick-quick scheme, but this person could be useful to my goals, so I decided to overlook that"

Its not a unique problem to NFTs, its a similar problem that a founder might face when, say, entertaining an acquisition by Meta.
