However, Satoshi did use an account on this forum, along with an email address. All connections to this forum logged his IP address/user-agent and other digital traces.
I don't want his identity to be revealed ! But I'm simply wondering how he has managed to evade the most powerful entities since 2010. Even with current anonymization technologies, the most prominent cybercriminals/activists get caught.
If Satoshi used an account on this forum, do you expect the forum to share his IP with the authorities? That would be a terrible thing if the forum administrator do such. I don't even think that Satoshi left a relevant IP address is everything he did online. His IP address on the forum might not really come from his original location since he is a genius, he can travel to a different location to do his business and if you go to those location you might not even find any clues about him.
