These URLs would then be sent to PhotoDNA to detect if any known CSAM was present, and matches would be sent to the Project Arachnid Shield API to have the results validated by Canadian Centre for Child Protection (C3P).25 Once instances of CSAM were verified, we would use their image embeddings26 to run k‐nearest neighbors (KNN) queries27 to find related images in the dataset.

I'm not entirely sure how k-nearest neighbors queries work.... What exactly makes another link similar enough? :marseyhmm:

After initial validation, we also implemented industry MD5 hash sets provided by the National Center for Missing and Exploited Children (NCMEC)28 and a CSAM classifier provided by Thorn29 to discover additional content not detectable via PhotoDNA.

They used government-funded file servers full of CP!!!

They use knearest neihbours on the image embeddings, not the links. Image embeddings already cluster by similarity in the embedding space when they're created so the nearest neighbours are visually similar. Visual similarity can mean a lot of things though, maybe useful to find other instances of the same image with different compression artifacts but I don't know if CSAM would be most visually similar to other CSAM, rather than legal pictures with similar color distributions and visual components.
