I am not sure how many would count the use of bitch an attack, unless its "you stupid useless bitch I am going to get you banned for this etc etc" kind of attack on someone.
If you kill someone and they say, argh, "what a bitch", or "dammit you got me bitch", that's different, really. It is an exclamation, rather than abuse against you. "Queer", or "gay" is becoming, or more to the point, has become a rather mainstream word. It is more of a gentle insult than a seriously bad one. Its no different these days to using "bloody hell", or "bugger", they used to be seen as "stronger" swear words in the past and are considered not really to be swearing these days.
The moderators are listed in teamspeak, they are listed there for a reason, if they aren't on, message them about the issues on the forum, don't just post up on the forum saying everything is broken. We can't deal with problems on vague posts, we can if issues are listed directly/specifically.
TL;DR: If its abuse and you are uncomfortable with it, message the moderators. If it is in game, screenshot!
