We have facial recognition technology that recognises black people as gorillas, and other face recognition technology that ignores black people.<p>Nudity recognition is going to be really hard to detect.<p>Since these children were using &quot;vault apps&quot; those vault apps would probably start to include bypass techniques.<p>And this ignores the sexual health stuff that children can validly search for.  You don&#x27;t want to block images of how to check your testicles for cancer, for example. (Although photographs are probably not helpful blocking the images would be counterproductive.)
