Looking for inappropriate words in customer data is always a risky business. Most times there is always a legitimate name or a place somewhere with that word.
Like if you see a city name called “Hell”.
Outside the English speaking parts of the world you will find “Hell” in Norway. It’s a village with its own postal code (NO-7517) situated in the Trondheim metropolitan area. Not at least at this time of year with winter on the Northern hemisphere it is surely considerable colder than the religious “Hell”.
But even in the English speaking world you will find a semi legitimate “Hell” in Michigan, United States.
