Interesting case. He says that he didn't decide it, someone decided it for him. It does sound like his family had been threatened.

When he came out saying this stuff, it did occur to me that he might have been pulling a double bluff - that he was Satoshi but by claiming it in a way that was unconvincing, it would take most of the heat off him. Now, many people refer to him as "Fake Satoshi", and they won't even consider the claim that he might be genuine. Maybe he played everyone.
