Yes, absolutely. He apparently goes to great lengths to "prove" that he is Satoshi, but when asked to sign a new message, answers "I’m not going to keep jumping through hoops."

Um, what? Signing a new message is a minuscule jump through a very large hoop, not something difficult or cumbersome or time consuming.

This fact alone is indefensible, smells of fake and should be enough to dismiss the claim.

If you're using a given key daily, yeah, it's not a big hoop. But I imagine Satoshi having his key hidden on an offline computer right now, hidden securely. Taking it out of vault must be a lot of effort.

But if you actually want to prove you're Satoshi, isn't that exactly what you'd do, rather than spend a lot of time on these other 'proofs'? What's the point?

Which is exactly why you wouldn't waste time signing a useless quote.

Just sign a message attesting that YOUR NAME is satoshi. No more work. Done once.
