Clinicians evaluate patients on an individual basis and would have to determine whether exposure to explicit images could diminish urges for a given patient
This is exactly what my comment earlier was talking about. I could see how using AI-generated images in therapy could useful, but just putting them out in the open is not something I think is a good idea. However, I definitely could see a response being that so few people are in therapy for pedophilic disorder, so we'd really only be impacting those who've already committed offenses and are being rehabilitated.
