Harrassed by impersonator

There was a guy in trade chat claiming he worked for Blizzard and that his friend still works for blizzard. I called his bluff and he started sending me messages saying he will ban me he also said he was going to find where I lived and "shut it for you" after he told me to shut my mouth.

The player in question's name is "------" and I have multiple screen shots of his harrasing and threatening comments. He, in multiple whispers said he would have me banned and kicked out of law school because he has my IP address and can now do whatever he wants to me.

At one point I stated that if his friend abused his power to remove me from game after doing nothing wrong I could make him lose his job, and apparently this is "threatening a game master." Which clearly was not the case.
