Wouldn't make sense to remove the entire scene? Doing the Japanese style pixalation/censorship won't help IMO when you watch some movie with your kid and people start moaning. If the movie includes sex and nudity it probably includes some similar adult language so a tool that works in real time that only is trained on porn will be probably terrible and a waste of time though some "entrepreneur" would probably try to sell you such a tool (I mean it is just gluing shit togheter like most tools this days)
