I don't understand the logic of these people sending the child pornography. Is it something along the lines of "I'll show Hunter Moore what a shitty person he is by spamming him with content that arguably should make me a shittier person for having possession of to begin with! That'll teach him!"? It's just sad that people are trying to get their revenge at the expense of the children who had the misfortune of being a part of those pictures.
I can't believe that those people didn't face serious consequences. They possessed child pornography, ffs, it doesn't get much worse than that. The people who thought it'd be amusing to do that are seriously messed up, what's worse is that they face no real consequences.
