Hacker may have gotten into the email account, but I have a feeling he doesn't have Satoshi's real dox.
Because, here are the 2 teaser images hacker put out:
Do you really think Satoshi would place an order on a ecommerce website using his Bitcoin-related email address, and give out his real identity like that? Hell no he wouldn't. And this was in 2013. No way he would go through all the trouble of trying to be anonymous, then make a online order with his bitcoin email and his real billing/shipping info. I don't doubt the account got hacked, but the dox can't be real based on this.
No, anyone could place this order and put his email. Probably a hacker wannabe thought it was funny to put Satoshi's email when he was placing the order. Btw, the teaser leaves the first character "A" of the name visible.
