      2) This test was put together with the help of the Australian eSafety Commissioner and several advocates and NGOs with deep experience with NCII and partner abuse. Check out their statements in the post.

      3) We are aware that having people self-report their images carries risk, but it's a risk we are trying to balance against the serious, real-world harm that occurs every day when people (mostly women) can't stop NCII from being posted.

      In recognition of that risk, we have taken the steps we can to protect this data and to only retain non-reversible hashes. To prevent adversarial reporting, at this time we need to have humans review the images in a controlled, secure environment.

      4) We are not asking random people to submit their nude photos. This is a test to provide *some* option to victims to take back control. The test will help us figure out how to best protect people on our products and elsewhere.

      A personal comment: this situation is a pretty good example of a problem I talked about at Black Hat this summer. Our greater infosec/privacy community, including the media, has trouble talking about imperfect solutions to serious problems.

      When there was a burst of ill-informed press around a crypto issue this year, there was an ability to self-correct, since the external experts who set the tone of the conversation understand crypto.

      The number of people outside of the big platforms who have to deal with abuse like this at scale is actually minimal. I think this is a good demo of why we need to continue to talk about these problems publicly to build understanding and trust.

      A quick note to everybody who says "calculate the hash locally": A) Photo fingerprinting algorithms are usually not included in clients to prevent the development of circumvention techniques. B) Humans need to review to prevent adversarial reporting.

      It's an open research problem, but so is post-quantum cryptography.

      You are lucky to work at one of the few companies with an excellent safety engineering team. Maybe let your fuzzers run for a couple of months while you try your hand at this issue? More infosec-safety exchanges are great for both sides.

          Plenty of headcount! Standing desk and all the turkey jerky you can eat just waiting for you, say the word. At a minimum I can get you a counter-offer. GSUaaS
