Code to add regex filtering to censor function

[gmerin]

I have some jerks (my fourth adjective choice and the first that wasn't 4 letters long) who insist on trying everything they can think of to get around the censor. I eliminated *all* the extended ascii character codes so now they are using variable numbers of spaces between the letters of words to evade the censor. I need to be able to apply regex patterns to the censor; has anyone attempted this yet? any hints, suggestions, etc. to approach this (besides banning the idiots since I generally try not to do that)?
