No. It's a legitimately difficult problem because there not all naked pictures of kids are illegal. The false positive problem is bad for business, but also generally bad even if the big social media was benevolent.

Moderators need to actually understand the context of the picture/video, which requires knowledge of culture and language of the people sharing the pictures. It's really difficult to do that without hiring moderators from every culture in the world.

But small federated servers can often align along real world human social networks, so it's easier for the server admin to understand what should be removed.
