This assumes that it's impossible to reverse the perceptual hashes used here in such a way that you could determine poses and coloration, for one. And in retrospect, you don't need to match that - you just need it to appear obviously pornographic after the blur is applied in order to get past Apple's reviewers. After that, the lucky individual's life is in the hands of the police/prosecutors. (I have to imagine that both real and faked cases will look pretty much like "Your honor/members of the jury, this person's device contained numerous photos matching known CSAM. No, we won't be showing you the pictures. No, the defence can't see them either." Can you imagine a "tough on crime" prosecutor taking the faked case to trial too? Would the police and prosecutors even know it was faked?)
