Are you saying someone will use it to create a CSAM generator? It'd be like turning smoke detectors into a nuclear bomb. If someone that smart wants this, then there are easier ways for them to do it. Analyzing the detector could let you tune normal images in an adversarial way that'll cause them to be detected as CSAM by a specific release of a specific model. So long as you're not using the model to automate swatting, that's not going to amount to much more than a DEFCON talk about annoying people.
If you have a csam detection model that can run locally, the vast majority of sysadmins who use it will just delete the content and ban whoever posted it. Why would they report someone to the police? If you're running a file sharing service, you probably don't even know the identities of your users. You could try looking up the user IP on WHOIS and emailing the abuse contact, but chances are no one is listening and no one will care. What's important is that (1) it'll be harder to distribute this material, (2) service operators who are just trying to build and innovate will be able to easily protect themselves with minimal cost.
You are mandated to report what you find. If the g-men find out you've not only been failing to report crimes, but also destroying the evidence they will come after you.
Note that this is specific to CSAM, not crimes in general. Specifically, online service providers are required to report any detected actual or imminent violation of laws regarding child sex abuse (including CSAM) and there are substantial fines for violations of the reporting requirement.
Wow. I had no idea. That would explain why no one's uploaded a csam detection model to Hugging Face yet. Smartest thing to do then is probably use a model for detecting nsfw content and categorically delete the superset. Perhaps this is the reason the whole Internet feels like LinkedIn these days.
Someone send you a meme that looks like a meme, you share it through messenger, the meme looks like something else to the messenger, messenger reports you to NCMEC. It's NOT police but they can forward it to police. As a side effect NCMEC gets overloaded helping more of real abuse continue.
