FB wants every detail about everything your life, and wants to only share rosy PR in return. That part isn't news.

What's worth repeating is how tone-deaf and stupid this is. Decision-makers inside FB are living in a bubble crazy and arrogant enough to make them think this is something to propose to the world.

It is a technical bandaid that could theoretically work if you ignore the real people inhabiting the real world who would be using it. Reminds me, in a different way, of folks talking about how printing PGP (then) hashes on business cards was a workable fix for the web-of-trust, only throw in nudie pics, even more nerd-arrogance and FB's brazen, repeated abuses of trust.

When FB offers to act as my agent, with a contract including teeth for improper disclosure of confidential information, they will be approaching Saul Goodman levels of trustability.

This is old: nowadays, to create revenge porn, someone can just grab your face photos and use deepfakes.

i.e. facebook doesn't need naked photos to stop revenge porn, just use photos of your face, which they already have

i.e. photo of your face appears on fb/instagram/etc in an unlikely place? auto-crop it to just that body and ask you if you approve. even better, offer a page listing "your photos that appear on other people's feeds and profiles". The algorithm would need to be conservative (i.e. err on the side of not-matching) to avoid leaking other peoples' naked pics to you. To thwart uploading previously-recorded photos/video, use the same tech as Face ID.

This would also be an excellent positive-PR partnership opportunity between Facebook, Google, Tinder, and the other top social media and dating sites.

I wonder what's their real agenda with these photos. You can never take what Facebook says at face value. Just like when they say they're only building shadow profiles on you for security purposes.

Forget their intentional use, what about the unintentional use?

"We're terribly sorry this database of photos submitted to prevent revenge porn was accidentally made public. We have fixed the security hole which made this possible, but still intend to keep and expand the database which was exposed. Thank you for your understanding and participation."

Or, imagine a new advertising filter popping up some new advertisements for you: "Have genital warts? Use our cream to make them go away!"

This would be a useful service if their system could detect signs of skin cancer. In terms of squelching revenge porn, I do not see how this would remove anything from non facebook servers. Is 4chan going to integrate with this? Are they really only using hashing? Simple hash checks are negated with trivial effort. If they are just hashes, why are users uploading anything beyond a hash? Example: virustotal [0] can ge…

Well, imagine how much revenge porn is being shared on Facebook and their other social networks because that's where the victim is. You don't need global buy-in for it to be useful. Raising the barrier can be useful. The bullies have to not just find another video host, but be bothered to actually do it. Watching my friend's little brother wonder how to do anything out of the same three Android apps he uses daily, I'…

I agree in principal with what you are saying. There are certainly cases inside of FB that this could help, assuming they are not just doing simple hashing.

In my opinion, I believe they should extend their service via an API or hash database that could be used by other sites to reduce some of the group raids on FB accounts and other social media sites to improve the effectiveness of this initiative. Imagine if CloudFlare were to uptake this database and show what sites were sharing a particular file, or even allow website admins to filter such images.
