A clever script could easily filter many words, and many common ways to cheat less advanced filters. And could even be used to red flag people for saying things that are commonly used with in-appropriate speech.

I went on classic, and it took me 20 minutes talking to a GP before I could find out that there actually are rules against all the things I saw within 5 minutes of getting there. I know that most of those things can be taken care of with scripts and filters.

I agree, that it should be mandatory. As you can see by the first couple replies to this, It's very accepted and expected already, It's a bad sign.
