Consider the difference between "Generate an image of Emma Watson", "Generate an image of Hermione", and "Generate an image of a female hogwarts witch and student". We're getting less and less specific, but those are all likely to get you an image of Emma Watson.

Your filter has to pick out that, while they did not ask for a specific person, the practical result is likely to be the same. That's going to be tough to get near perfect.
