Not to mention the fact that if you get too clever with your 'badword' filter, you will inevitably wind up filtering legitimate words. This is often more annoying than not having a filter at all.

Can you guess why *all* of the following lines might not pass a badword test?:

A: who reads the news?
B: if they *publish* it, flip reads it
A: flip is so well-read
B: yup, pen is too, but he's a bit cocky
A: probably cause he drives a FiretrUCK, You!

"bad words" are everywhere, if you look hard enough. If you look too hard, you will wind up irritating the polite people, and giving the naughty potty mouths one more way to mock you, and your 'clever' filter.
