The conspiracy YouTuber making the claim was attacked and slandered heavily after making the claim despite convincing evidence that wasn't disproven:
1 Same English typing mannerisms
2 Misspelling the same words
3 A conspicuous gap in his career while Bitcoin was being developed
4 entering the bitcoin scene in forums very early acting authoritative
Not to mention
5 A history of working on bitcoin-like technologies: "hashcash"
6 early involvement with the cypherpunks
I'm still convinced its him.
