no edit: i am not going to go any farther, i do not believe that revealing your personal information (given that i have found it) is reasonable, nor is "revenge" morally correct. think what you will, but what you did was a complete richard move. the fact that you're taking the ideology that "it doesn't matter" bugs me above all - you could've ruined somebody's life. it doesn't matter that you're half the world away from him - the fact that you keep mentioning that as a reason why you don't care just shows how self-centered that you are.
Seriously who even are you
What did you do
he investigateed another guy, made a different thread ("Sorry, Not Sorry") about how little he cares that he revealed another user's personal information. moreover, he spent several pages being a complete richard about it - basically a textbook jerk who doesn't know how to say sorry.
