This article and also this one at https://www.bbc.com/future/article/20250306-inside-youtubes-hidden-world-of-forgotten-videos were interesting reads. It would be nice if they offered some pointers on how to better find this stuff.

One of the interesting things of exploring other languages on especially social media is that you realize just how un-moderated the US platforms are for anything but English. When people talk about Facebook advancing genocides, it’s the platforms not bothering to moderate non-English content but still applying their maximum-engagement algorithms in those spaces, so you get this snowballing of negative content.

Be wary if you go looking for non-English social media (it’s actually not hard at all, you use a VPN and change either your OS or browser locale settings), because you can easily end up seeing some grisly stuff.
