I don't know. Everyone's talking about trolls. Not everything on your list has to do with just trolls.

It is, in my opinion, pretty natural to be curious about what Jennifer Lawrence looks like naked. It is unnatural to, say, follow her around and try to take pictures, which is why very few people do that. But if the pictures are just sitting there on reddit, then tons and tons of people are going to click. It's not right, per se, but it's understandable. I clicked. I had this vague hope that Lawrence's cell phone pictures would be tasteful, because I like her and she seems more in touch with normality than most actresses, but they were instead kinda creepy, and I was sad. I like to think that if I took cell phone pictures of myself naked, I would at least smile, use good lighting and, you know, try to make myself look more attractive than with clothes on. I'm not sure why so many people who send pictures of themselves around don't do that. But that's an irrelevant digression.

The point is that I don't feel like proving your opinion, because I disagree with it. Social norms exist to hold in check the many vices of humanity. It's all in Mandeville, although he took it in entirely the wrong direction with his talk about positive economic benefits.
