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.
