Social Media Nudity

Should Facebook or Instagram or even Youtube allow nudity like X does? I see lots of ladies that find a way to show some skin. One way is to wear next to nothing sheer clothing in videos. Lots of this on youtube. The nudity disclaimer is pretty funny, "the purpose of the video is to show clothing functionality, not sexual gratification", so basically sheer tops and bottoms with full nipple and pubic hair displayed but not nude. I don't mind, just find it to be stupid.
Another is when a non pregnant woman pops out her full tittie and then pretends to breast feed a doll.
What the fuck?
