JCaptcha - How to avoid profanity/profane/obscene words

We have implemented JCaptcha in our website. But we came to know that it randomly generates some obscene words.
Is there any way we can block the profane content?

Any help will be highly appreciated.

Thanks,

Personally I wouldn't worry about it.

Thanks for the response David.

We have a pressing business need that we need to avoid this. I looked at the link that you posted.
Its about Changing the Captcha generation configuration. How can I be guaranteed that this new method doesn't give me any profane words?

By implementing a word generator that doesn't ever return "obscene" words, although quite frankly if you're using both random chars and numbers it seems *extremely* unlikely you'd ever get an "obscene" word.

Thanks David. Unfortunately we had an instance that we did get a call reporting profanity.

Then you'll just have to post-process the text creation and make sure there's nothing "obscene", although people can find something obscene in just about anything, so good luck.

Thanks David for your timely input.
