Too true. I depend on hacker news for many things, but being secure is not a bet I'd put money on. There are ways of making more provable claims in either direction--unless it's either attested multiple times in the past (so as to be difficult to doctor) or it's cryptographically signed or there's a convincing prosecution, I don't think we'll be confident about it.
I would bet that anyone who is already very geeky and just happens to be called Satoshi Nakamoto has a much higher than normal chance of being a bitcoin early adopter.
If Dorian was a member of the group that eventually birthed Bitcoin, isn't it realistic that he'd be an early adopter, even if the pseudonym wasn't quite his?
It's a desperate attempt to mislead.
