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.<p>Users might consider saying "I do not want my images being public" and can be prohibited before posting.<p>Taking it down <i>after</i> it's posted is useless, it'll be in caches all over the world and by that time, it's too late.<p>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.<p>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.
