LJ auto-filter avoidance?

[johnridley]

It looks like LJ automatically re-writes certain key words in order to avoid getting trapped by censoring filters.
I copied in "sex & the city" for the TV meme, and in the HTML after saving and going back in to edit it, it had changed the first word to this:
<script>document.write('s','e','x');</script>

I put my journal settings on "No Adult Content" and "Do not filter my results", did the post, went back to check the post's HTML. I got this: Sex & The City. So, yeah.

That didn't work out right, but you get the gist. It didn't change the word sex.
