If FBI or CIA was eager to find who the hell satoshi is, i am pretty sure they they would identify him in a very short time.

In fact, either they already know who he is or there is no need for all this because they are (USA) satoshi.

Do you really think that an anonymous forum account would protect you from the FBI? What about the other admins? If the FBI knocks (or knocked) their doors, they would sing satoshi's identity like birds.

He dead? I don't think so.
