I think you need to rethink this comment. There have been many stupid posts in this thread to justify unethical behavior, but that does not mean bullying is not relevant, nor should you be suggesting people quit the game.
Edit - After discussing with Zaup, we disagree on what exactly you meant. Are you saying that bullying doesn't exist and anyone who thinks otherwise should quit? Or are you saying that bullying did not happen in this case and if you think being hit is bullying you should quit?
