Answer 2.
Personally I think it could be Robert Tappan Morris Jr: Made the first internet worm - 1988.
Unless a person is willing to come out and sign a message with one of the addresses "known to be Satoshi's", nobody will take him really serious.
Writing style, background and so on.. will be probably checked afterwards.

Since Satoshi Nakatomo wants his privacy, we should give him/her that respect, let's forget a subforum for unveiling what is not lost. Who knows, he might be the guy in the picture below posted by @NeuroticFish. I've always pictured the same person in my dreams, and coincidentally his image reads 'Satoshi' among the pictures there. What a coincidence!
