Not really. This is very likely just a single troll. He probably got the idea of using satoshin@gmx.com to post to p2pfoundation.ning.com from my post here. The dox stuff is probably fake.

I for one am disappointed in the level of trolling displayed here. He could have done something amazing with Satoshi's email address, but instead he made a couple of lame jokes, and now everyone knows that the email address is compromised.
