A deepfake is defined as any sophisticated AI-generated image, video, or audio meant to mislead. For this question to resolve positively, it must actually harm someone, not just exist. Valid forms of harm include but are not limited to costing someone money, or making some specific name-able person genuinely upset (not just “for all we know, people could have seen this and been upset by it”). The harm must come directly from the victim believing the deepfake, so somebody seeing the deepfake and being upset because the existence of deepfakes makes them sad does not count.
