Instagram is serving me literal porn when I browse shorts (for instance women showing their private parts). It's amazing that they are unable or maybe don't want to block it.

Facebook basically has sexual content spam as in the OP article all the way.

It's to the point I'd never open either app when in public.

I'm not convinced they care about moderation outside of legal necessity.
