Oof. Apparently my irreverent tone was not well-received. I'll be more sober about it. A cryptographic hash is not proof that data was signed by a particular individual, unless you know for certain that individual is the only person who has the key. That is a hard standard to meet with a dead man when the key has demonstrably been used after his death. That transaction in 2017 means that someone besides Finney simply must know Finney's key. Anything signed by this key cannot be trusted to have come from Finney.
