I am having the same problem. I’m not trying to censor profanity but prevent this phone number this spammer keeps posting on our forum from being used. I am using the Akismet plugin but some amount of spam still gets through every night. Since the spammer has only used two different phone numbers in the entire time they have been spamming, I figured censored words would be an easy way to set them back. However, they just keep posting all of the information in the title of the topic and fill up the body with just random characters.
