Who's to say who really did it? Maybe it was him maybe it wasn't. AI can do marvelous things now days. I'm not suprised if it did happen, because everyone wants to protect their reputation. One thing that has me wondering though and maybe they are two different thing and maybe not is if you can mine Bitcoin and every other crypto-currency in the blockchain then what makes us think everything we put on here can not be broken into if someone works hard enough at it? I guess that goes to show how much faith and trust we put into this technology now days, but if it makes it seem safe from people tampering with whatever we post, then people are more likely to use it.
