The naked truth about Facebook’s revenge porn tool
This is absolutely spot on.

If Facebook wanted to implement a truly trusted system for revenge porn victims, they could put the photo hashing on the user side of things -- so only the hash is transferred to Facebook. To verify the claim that the image is truly a revenge porn issue, the victim could have the images verified through a trusted revenge porn advocacy organization. Theoretically, the victim then would have a verified, privacy-safe version of the photo, and a hash that could be also sent to Google and other sites.

Facebook asks users for nude photos in project to combat revenge porn
The photos are hashed, server-side, using the PhotoDNA hashing algorithm. This would have been way way better if it ran locally, on user's phones, instead though. Interesting to note that PhotoDNA claims to have a "1 in 10 billion" false positive rate according to https://www.itu.int/en/cop/case-studies/Documents/ICMEC_PhotoDNA.PDF
