I'm (mostly) all for it. I like to keep the signal-to-noise ratio high, and keeping a lid on pointless foul language helps. On the flip side, of course, the Canterbury Tales wouldn't be the same without certain words now considered extremely foul. No word is foul on its own, it is idiom that makes it so. That being said there are certain words that are almost invariably used poorly, so I do have some words filtered so that they automatically get replaced with cartoon (^%&!#$) curses
If you have words you would like on the list, send me a PM and I can add them. Of course this sort of thing is easy to subvert this by doing things like using a "v" in place of a "u" and whatnot.
