> Example: How does a researcher test whether algorithmically-classified illegal imagery stored on user devices is being scanned and reported home to Apple's servers, and what those bounds of AI-classified criminality are? (presumably with respect to what is illegal in the user's jurisdiction) I'm not an expert in AI so this might be totally off base but I feel like you would be able to use an "intersection" of sorts for this type of detection. You detect children and pornography, the children portion trains it for age recognition and the porn portion trains it to see sexual acts. Slap those two together and you've got CSAM detection.
