I wonder when the email was compromised, and whether it could have been used to make the post on p2pfoundation.ning.com. (Edit: I was referring here to the Dorian Nakamoto post. After I posted this, there was another p2pfoundation.ning.com post.)
Do you think the "not Dorian" post was fake? If yes, the same hacker or a different hacker than now?
I would doubt it was fake. It was too muted to be a hacker. I think it was the real satoshi and he wanted to make it so the satoshi who was "outed" would not get the unwanted attention he was getting
