I had to work on implementing fairly well-known advertiser's banned-words list into our system recently. Their system is incredibly stupid. For example, they'll ban the word "Dimethltryptamine", but "Dimethyltryptamine" (the correct spelling) is allowed. You're not allowed to use the word "bulldog" under the Pets category. You can't use the word "dragon" under Jobs. It seems like they just have a form that visitors to the site can use to link ads containing "offensive" words and the system will automatically add it to a list.
