Wouldn't this be an actual ideal use case for facial recognition? Apple wanted to do CSAM before upload, Twitter could do consent-checking before posting. Users might consider saying "I do not want my images being public" and can be prohibited before posting. Taking it down after it's posted is useless, it'll be in caches all over the world and by that time, it's too late. For example, every reddit post ever posted (or near enough) are scraped in real time (pushbullet, bigquery etc) so the take-downs need to happen before it hits public APIs. I also think we need to enforce consent, and begin taking action against tech firms - if I did not consent and they allowed it to be published, they should be held to account. They need stronger measures to ensure consent was freely and fairly given.
