That's the weak evidence. Nobody cares that they both like open source and freedom, half the cypherpunks list fits that.

The parts worth engaging with: Back described a system combining Hashcash and b-money with inflation adjustment and public timestamping on the cypherpunks list between 1997-1999. That's basically Bitcoin's architecture, a decade early. He was one of the most prolific digital cash posters for years, went silent when Satoshi appeared, came back when Satoshi left. And this person who independently arrived at the same technical design also independently landed on the same Napster vs Gnutella analogy, the same celebrity email filtering idea, and the same FDR gold ban trivia.

Any one of these is a coincidence. At some point you have to ask how many you need before the simpler explanation wins.

This article is a great example of "strong + weak = weak".

I only made it to the interesting stuff because of Carreyou's name, otherwise I would have stopped.

The email timing and lack of email metadata were also strong, in my opinion. But all of this nonsense like "Wow, these guys both talk about PGP??" distracts from it.

All of those similarities can be explained by Satoshi having read what Back wrote.

You need someone who read Back's obscure 1997-1999 cypherpunks posts about combining Hashcash and b-money, implemented exactly that system a decade later, independently came up with the same non-technical analogies and trivia, wrote with the same hyphenation errors, and then happened to be active during the exact window Back went silent. The more you flesh out the "someone who read Back" profile, the more it just sounds like Back.

Someone who has read his material would be likely to repeat the same analogies and trivia.

As for the hyphen errors, they are common for people for whom English is their second language. I commit hyphen errors similar to what is described all the time because English hyphenation makes absolutely no sense. In fact, reading the list of examples, the mistakes listed makes more sense to me than the correct way of writing those.

I also switch back and forth on a lot of the phrases the article mentions.

I also switch back and forth between US and UK spelling, because I learned UK spelling at school, but was far more exposed to US spelling in practice.

This seems to me to be exceedingly weak.

		At some point "Satoshi was a devoted reader of obscure 1997 Adam Back mailing list posts who shares his hyphenation errors, his Napster vs Gnutella analogy, his celebrity email filtering idea, his FDR gold ban interest, his 'burning the money' metaphor, his 'Achilles heel' description of DigiCash, his 'better with code than words' self-assessment, his energy-vs-banking defense, his British spellings mixed with American ones, his double-spacing habit, his it's/its confusion, his sentence-final 'also' tic, his 'proof-of-work' hyphenation, his WebMoney references, and who went active the exact week Back went silent" is just a longer way of saying it's Adam Back. I'm not sure I agree with that, but it's what I came up with after challenging myself to read the article in toto again and note 1 by 1. It's clear it's beyond a couple tics everyone has, and when you combine that with the starting set being ~500 instead of "all 8 billion people on earth", well, it's worth mentioning.

It's been extremely widely known that whoever created Bitcoin had a strong interest in Hashcash, and perhaps created that or worked on it, for years and years. If that's the only smoking gun, why didn't we identify Satoshi long ago?

		You're right, "interested in Hashcash" describes dozens of people, and has been a known Satoshi filter for years. The new claim is more specific: between 1997-1999, Back proposed combining Hashcash with b-money, adding inflation adjustment via increasing computational difficulty, and using hash trees for public timestamping. That's most of Bitcoin's architecture in one package, a decade early. The number of people who proposed that particular combination of ideas is much smaller than the number who were merely interested in Hashcash.
