By the way, there was another message by "Satoshi" recently, denying that he was Craig Wright -- and then adding "We are all Satoshi". That last part is obviously something that Satoshi would not have written. I can only think that the hacker is aware that everybody is aware that the account has been compromised, and does not care to pretend anymore.
Theymos is the one who pointed out that that email was spoofed, and even posted the IP from which it was spoofed:

This IP is obviously a TW customer in Wisconsin, where Theymos lives. How much more obvious does he have to make the joke?
