I guess you mean the chat room, because all posts on the main site are censored, eg ***
Also, swearing is a bit of a regional thing, eg damn and hell are not swear words in the UK and we have some swear words like w**ker (manually censored) that are unknown in the US.
If people are swearing it's usually not the words that are a problem but the fact some one is insulting people. I will look into filtering words on the chat though. I'm not gonna dock points or anything.
