profanity

What is the correct way to strip profane words from a string given: 1) I have a list of 100 words to look for in an array of strings. 2) What is the correct way to handle partial words? How do most people handle this? For example the word mass. Then sometimes a partial word is also bad - assume foobar is an extremely profane word I may want to disallow foobar and foobar* and *foobar. So do you put all the words into a single expression or loop through the list? What's the right way to tackle it? I'm using Groovy/Grails but any modern languages examples welcome.

Looking around with google I found this one, and it's a start, but nothing more. Yes, I know that this kind of filters are easily escaped... but the client will is the client will !!! :-) The site will have to filter out both english and italian words, but for italian I can ask my colleagues to help me with a community-built list of "parolacce" :-) - an email will do. Thanks for any help. I didn't see any language
