Orly? If bad language hurts any of your feelings, you shouldn't be playing a mature rated game that includes blood, killing, and FEMALE CHARACTERS WITH THEIR TlTS HANGING OUT
There's a problem in your thinking.
Blood, everyone does have.
Killing is necessary for survival (meat mostly, but veggies have lives too...albeit immobile and probably not really conscious).
Nudity is sexy. Sometimes...And natural...always (though not always good, I guess).
All of these are part of the game and when you start playing it, you can accept them or not.
Bad language is unnecessary, it have no purpose, it is displeasing in a normal conversation. Furthermore, it is not part of the game. When one starts the game, he is not warned that there will be people swearing. Quite opposite, if the person did read the ToS, he/she may think there are none, as they are against the rules.
Also, other people doing something wrong does not give you any special right to do it. If you see em doing it then report and move on. Like someone reported you and moved on. That simple.
