We call this the Scunthorpe problem. Stupid "rude word" detectors use simple rules that fail on actual words.

Way back I was working on a loyalty card system that had the entire UK electoral roll and Post Office data and we had to validate people; names and addresses. A "comedian" decided to sign themselves up for the system using a stupid name, and when the loyalty card duly arrived at their (correct) address with their (incorrect) name, they went to the papers and it became a slow news day human interest story.

We had to implement a Scunthorpe filter, and that was really difficult. We ended up with a human looking at the data and hitting a button if they thought this was a made-up "funny" name or address.

You would be amazed at English place names and surnames. Velvet Bottom is a real place in the UK. There are many people wandering around with names that you can't say in polite company.
