Oh c'mon - ****, ***, ****, & **** are definitely slang that's considered cursing... Really all of them are curses, just used as insults, unless you want to go by the literal "take the lord's name in vain" definition... (when I was typing the previous sentence, I misspelled "insults" as "insluts"; forgot to include one like that...) Try going to some school and saying any of those, see what happens...
And if it's the aforementioned literal definition, then "damn" should be censored - one of my funny memories is of a guy who was offended by all the cussing / taking the lord's name in vain while listening to us talk, got fed up, and finally shouted out, "stop cussing, damn it!"... Not tongue in cheek, he inadvertently cussed while complaining about cussing...
Going to add some of these to the filter. Lets be honest, whether or not its a swear by whatever definition, these aren't exactly socially acceptable words lol.
