Yeah, any viable list of swear words has to include "damn" (and derivatives), "hell", and "ass" (and derivatives). I'd even go so far as to say that "crap" and "retard" (and derivatives) are sufficiently unprofessional that they belong on the list.
You'd want to whitelist against the Scunthorpe Problem though.
Damn is a curse, but not actually considered a swear word in most parts of the world.
