The laws on child pornography are obviously formulated with pedophilia / child molesters in mind. Unfortunately, the laws ended up being a typical moral panic mess and ended up being overly harsh and broad. Minors charged with child pornography for sexting each other completely undermines the original intent of the law, in my opinion.

I'm curious what the laws / regulations would be for general social media, image hosts, and other businesses that host user content. It's pretty much a given that at some point, there will probably be some illegal content uploaded onto it (including potentially child pornography). In some ways, a Tor exit node sort of falls under that same boat: you are indirectly passing information generated / requested by users.

Now, Twitter or Facebook doesn't going to get raided / computers confiscated every time an illegal image passes through their network. But I'm sure the police may ask questions during investigations (and I'm sure the companies comply as best they can). So I honestly think what happened here is fine. (I'd think differently if the police automatically confiscated computers and trashed houses of Tor exit nodes for no reason.)
