I'm not surprised at your response, but Guardian should have had someone a bit more knowledgable talk to their writer before they went off on this particular rant.

Taking hashes of files to find/block/delete them is perfectly legitimate and has been in use in industry for ages.

The writer has just added their ignorance to turn it into a huge drama.

I don't think it's the file-hashing technology that people are concerned about

I feel like I could... TAKE ON THE WORLD!!
What would be a better way to remove these images? off the top of my head, it might be more sensitive to give people the tools to make the hashes themselves, which they could send to facebook, rather than sending the images.

Even then a human would have to review it at some point to see what matches they find in case someone sends a hash of Trump or something.

Apart from all the other reasons why this sounds like a very dodgy idea, surely all a revenge pornster would have to do is to crop and filter any photos before uploading them and the software would then not be able to recognise them?

Image recognition: it would hash features within the image, not the whole file. Cropped images would still trigger an alert.
But I don't think it's a workable solution.

I'd like to see FB employing AI to identify nudity.
If detected, the submitter should be challenged to confirm their contact details, and maybe even pay a fee and/or deposit ; returnable only if the image passes moderation (this allows some nudity for educational/artistic reasons).

There are a few topics to talk about here. The first one is not to put yourself in this position to begin with, especially women. Do women post naked photos of ex boyfriends? I think it must be mostly the other way around.

I thought FB had a strict policy of what type of photos they would allow to be shown. A friend of mine recently posted photos of her double mastectomy and was banned from FB for revealing bare breasts. After she pointed out that was not possible she was reinstated.

Are there not laws in place to prevent this type of thing? If there isn't there should be.

They do but it's not accurate.
