I grew up with the internet, I've heard it all. My experience was far from perfect. I just learned to deal with it and not expect the whole internet to change. There's a long list of solutions to this problem. Block them, mute them, don't engage, log off, create a new account, etc..
At the end of the day, nobody is going to protect you from the bad things that can happen on the internet. It's up to the individual to protect themselves and not take morons so seriously.
Where did I say it was ok? It's obviously not ok, that goes without saying. You seem to be focused on what happened and missing my point. This is the reality of the internet. It's been that way my whole life. As long as you can remain anonymous people will do horrible shit. They can ban as many players as they want, it's not going to change shit. Trying to force people to behave will never work.
