The way it works is people report CP to a third party organization that fights CP. A hash of some sort is recorded in a central repository that is used by many services including every major social media company. Those companies then use it to delete/ban/etc users who post images matching those hashes. Generally, they also work with law enforcement.

In the current iteration they are not using AI or anything to identify "bad" content. They are matching hashes for files on on your device against known bad hashes/content.

I'm not trying to convince you one way or another about it, just clarifying what is happening.

This is misleading as these are not what most technical people would think of as a hash. These are "perceptual hashes" that can compute a distance, instead of a boolean equal/different, leaving space for false-positives instead of extremely rare hash collisions.
