I know Realbad was selling accounts, so won't exclude the possibility he could scam you, but Arthizan is not a scammer FOR SURE. I know him and hes the best dude I ever met, and among most fair players on wow.. So yeah, you are wrong about him.
Donno bout Realbad, I can't say I believe you, but I can't say I don't too.
But to actually kick him, I need profs (screenshot or video or whatever) or more people who could confirm your story..
This way or other, you could have stayed in LoH with 1 char at least :/.
Peace and sorry for what happened.
