I'm going to assume that's because you play with a very limited number of social types, perhaps only CSS?

The people I hang out with to play games never (or very rarely) swear. On of them is a BF1942 clan I belong to, which happens to be composed mostly of high-school or younger kids (the 7th grader has the worst attitude and happens to be quite stupid). They discourage swearing and enforce it when necessary, but there hasn't been much of a problem with it.
The other is a Raven Shield team or "family" which I frequently play with composed almost entirely of adults (since they require $10/month from each member to keep their servers up) and they warn/kick anyone who swears on their servers.
