Any normal person would have told people about the giant programming project to which he dedicated 2+ years of his life, and these people would have eventually blabbed, so Satoshi must have been unusual. I always pictured him as a shy but brilliant guy who doesn't normally deal with people. "I'm better with code than with words," he said. Maybe he left when he saw that Bitcoin's future had a lot more social problems than technical ones.
I don't believe that Satoshi was a group of people. I was here when he was active on the forum and I directly communicated with him a few times, and I got a distinct impression that he was one person.
Why not releasing these IPs so that we can make a Map of where he was at this time. I am really good at investigating the net, I am a php/mysql programmer since before 2000!
I cannot believe Satoshi always used Tor... nobody is perfect, and you are always doing mistakes.
Anyway if you think that these are all Tor, then why not releasing them? IP address will not give precise informations like the exact address where he was staying. But these could help to locate him globally, and specially prove that he was in the USA CA at the time some others who are claiming that they are Satoshi were in Australia - that's just an example.
Send them in private to me, and I will give you my feedback and what I find. Then you will decide if it is worth publishing it or not?! But why keeping them?
