You could always stop people from swearing by removing the chat text altogether. After all, who needs to talk to other people when all they're doing is levelling?

Ahem, seriously though, there's not really any way you can stop people from swearing, except for maybe imposing penalties for doing so, but then you'd need some sort of swear police.

Swear filters can only do so much, since people can obviously get around them, like if "pancakes" was a swear word, all they'd have to do is say p ancakes.

The best advice is to just ignore them really...:-/
