I suggest we all leave "Toil" alone because he likely had nothing to do with this whole ordeal. By posting his personal information here and talking about paying him a visit etc... you're doing exactly what the hacker wants.
Good point. He still might have an idea of who would have or could have done this. Additionally, he has IP logs of his visitors, they could be used to collaborate the hack on Ozcoin, and the attackers IP might have also visited a few specific locations prior to the defacement action.
There's a TON of reasons for him to be spoken to, none of which have to do with him being the culprit but most of which have to do with forensics.
I just spoke to his father. I called the home phone number at because the mobile was disconnected. I asked if I was speaking to Joshua, and the guy who answered said he was his father. He sounded pretty displeased to get my call, and rightfully so because it's 2AM there. But he was still as helpful as he could possibly be.
I explained the situation as best I could and he told me he had no idea but he knew Josh had done some trolling stuff before on the Internet... that doesn't help us, but I still really doubt this is the kid.
I apologised for calling so late and let him go back to sleep. I probably got Joshua in trouble, regardless of whether or not he is the culprit. I feel kinda bad for that, although the kid does seem like a bit of a jerk anyway.
