Umm, are you sure about this? What if somebody says "I had to brush it off"? Will your software filter that? If you code it to avoid phrases like this, will you allow the "tithe"? How about "Shiite"?

I could likely sit here all day and come up with silly examples as to how this filtering scheme will filter more than you intended.

I could also show clever ways to still swear that most people would understand. I will not, however, profane the Monastery in that fashion.

What about historical references? How many of us, as we get ready to press the rest button and reinstall the server have shouted "damn the torpedoes, men!"? okay, I will admit I am likely to be in a minority on that one :)

My understanding is that most languages are far to context dependant for this kind of filter to work. I also freely admit this in no way helps answer your question, but I firmly believe there is no solution beyond compiling a list of Carlin's Seven Dirty Words and using a word boundary regex - like 

  /\bdamn\b/
