There are hundreds of them (just search by hashtags in the posts above). Of course same set of videos/pics repeated over & over, but my point is that such stuff is present all over Twitter & FB and anyone accessing those platforms can stumble upon them. Twitter doesn't even seem to put them behind a "Violent/NSFW" click-through.
I don't see how nudity can be more damaging or pernicious than such content.
For the first link I see this: "The following media includes potentially sensitive content. Change settings"
