Yeah, Facebook's blog post makes me wonder what all the stuff they report actually is. When people say CSAM, I think "kids getting raped" but apparently there's stuff that people find humorous or outrageous and spread it like a meme (and not like pornography).

"We found that more than 90% of this content was the same as or visually similar to previously reported content. And copies of just six videos were responsible for more than half of the child exploitative content we reported in that time period."

"we evaluated 150 accounts that we reported to NCMEC for uploading child exploitative content in July and August of 2020 and January 2021, and we estimate that more than 75% of these people did not exhibit malicious intent (i.e. did not intend to harm a child). Instead, they appeared to share for other reasons, such as outrage or in poor humor (i.e. a child’s genitals being bitten by an animal)."

Based on this, I wouldn't conclude that FB is the platform where people pedos go share their stash of child porn.

Their numbers also include Instagram, which I believe is quite popular among teenagers? I wonder how likely it is for teens' own selfies and group pics get flagged and reported to NCMEC.

> Facebook made 20.3 million reports to NCMEC in 2020.

Which appears to have resulted in what... 5 prosecutions?
