You all can probably understand why these lists err on the side of false positive, rather than false negative.

There's also the occasional fun false positive, such as a reply to a review from a client that would include a URL with one of the "bad" words as a URL token: e.g., "To learn how to clean your vacuum, download the manual at www.manufacturer.com/download?product=123&ass=abc" - where "ass" is some abbreviated variable name that ends up causing replies to get rejected.

(There's also some really, really fun words in some of those lists that I have no idea how they got there. My favorite one is actually from a different company that maintains a word list: N.I.P.P.L.E.S. Yes, all capital, with periods in between the words. Highly specific, and I'd love to know what was the original trigger for adding that to the list.)

Maybe if I use this list ...
