Would anyone who has ever read posts from Satoshi on this forum or private correspondence with any of the developers really think that CW is the real Satoshi even if he signed a message from any BTC address believed to belong to Satoshi? At some point, we have to accept that it may happen that someone will come into possession of the private keys of those addresses, which means that even a signed message cannot mean that someone is the original owner.

According to everything we know about Satoshi and CW, they are two completely different people in every sense. CW is nowhere near intelligent enough to play the role of Satoshi, and he shows that every day with his forged evidence - would someone who invented Bitcoin be so incompetent that he couldn't forge a single document in a way that leaves even the slightest doubt of authenticity?
