I used to participate in threads like this one with my own opinion and arguments of who is really Satoshi. I don't anymore, and would urge others to consider doing likewise. My concern is that it brings real-world risk on the heads of those people who, rightly or wrongly, are nominated as possible "Satoshis." We don't need some deranged (or non-deranged) criminal kidnapping and torturing any of the possible Satoshis to try to get his private keys, or the widows of those nominees who are deceased.

Satoshi obviously wanted privacy, and we have good reasons for respecting that. It would not be good for bitcoin if he were outed against his will, or worse yet if something was done to him and it made the headlines.
