I see no reason for claiming to be satoshi nakamoto while he is not and he tried the best to make sure that the world believed he is satoshi but on the other hand he failed because his claim werent back up with some facts that he is satoshi or even signed messages from his bitcoin address or make some transactions from his wallet to prove he is Satoshi, then fine, he could have won the battle, but instead fighting a blind battle with no facts to show he is nakamoto.
BTW, 12 months is actually very pitiable to him otherwise, country like ours he could be sentence for 6-10 years imprisonment for allegedly claiming what he is not, anyway that place would serve him as a resting place to enable him use his right senses.
That's actually true, if he was really satisfied Nakamoto there would have been proof to back ul his claims including making a transaction from his wallet containing his 1m bitcoin, as that will make it easy for people to believe him. Or he could have explained more technical aspect of bitcoin but obviously he is claiming what he is not. and we all knows a proof real satoshi nakamoto. The appearance of satoshi in bitcointalk forum here shows he was the real satoshi Nakamoto even without a physical appearance, because he answered some difficult question which new developers could not answer or could not have known without him. and until today his messages are still very lively and important, which no one else would have answered such question if not him. There are signs to proof a real satoshi but not ranting and forcing to be what he is not.
