Last time around, he peddled fake proof. A deliberately backdated PGP key trying to look like Satoshi's. The key also reported being created on a date when the software it was created with didn't yet exist. (Keyservers will happily accept keys that claim to be generated in 1992. Some publications that ought to have known better still accepted it back then, until it was pointed out.)

Still looking at the page you posted in the edit, but not yet convinced.

Wright goes into a long post explaining public key crypto - to me it looks intended to bedazzle more than inform - but as far as I can see he does not produce a signature from any of the genuine keys associated with Satoshi.
