If this were for online games, they'd need a full team to update the slang people come up with 24/7 to overcome the electronic ears. Also, what about childish phrases that contain no cursing? Such as 'I slept with your mother' to reference another post. If they want that to be effective, it has to be more than just a program listening for specific words because there are so many ways to say the same thing. Hell, even talking like Yoda could get past simple programs that look for specific phrases

All in all, this would be good and interesting.
