"That must've been a pretty disgusting story to investigate."
Please, this is limited to law enforcement. DO NOT TRY TO INVESTIGATE THIS yourself. Looking and finding CP could be considered a crime already in your jurisdiction.
At the same time, citizen investigations can be powerful things.
Investigating corporations for flippantly allowing child abuse materials to be indexed and distributed on their platforms should never be illegal. The fact that Israeli investigators did this research, rather than Americans (Google is an American company) shows that our own low enforcement clearly isn't doing it's job here.
I have a toolchain for finding child abuse content on Youtube, and I use it to report videos to Youtube for takedown. It's absolutely insane that I can be held criminally responsible for finding this content - but Youtube is immune from consequences hosting it.
Some of the videos I have found had millions of views.
Many that I have reported have not been taken down.
