I touched upon this in a comment
Looking around the idea that the Tumblr is possibly a creation by someone Neetzan knows — how else would he know about a day-old Tumblr with 20 posts, if it wasn't from a tip — the majority of images on the root Tumblr appear to be of people too young to drive.
Other than making fun of them, what purpose does the Tumblr serve and other than being a bored tween, why do these kids deserve ridicule? What purpose is being served by shaming them and linking their social media on a Tumblr and then mirroring those links on a multi-million dollar, international blog with tens of thousands of views?
An argument might be made that the young people are using social media and it's a public forum, which would protect the re-poster's right to republish, but as I said in the comment
Not to mention, how is this different from bullying?
A bunch of grown-ups are making fun of kids.
