I revealed a "friend's" reddit account detailing his weird fetish
What good does exposing your friend do?
I hate the guy and I wanted to ruin his life
Maybe he did not want that account out in the open yet. You should apologize because it is wrong to unwillingly reveal things that personal about people.
Nah, his fetish was pathetic.
That is not your place to decide that. What you did to your friend was wrong. You should have waited until he was ready to expose his reddit account before doing it for him.
