Who hasn't been in a situation in which a goofball friend emails them porn? I spent the better part of my college days receiving pornographic images of transgender people, grandmothers, large groups of friendly gay fellows, amputees, little people, and those with weak bladders from one of my friends -- who, in retrospect, had a lot of dysfunction in his life. To a very specific kind of person, nothing is funnier than sending pornography to someone whom they know doesn't actually want to receive it. This person is often called an "unfunny asshole." But there are a lot of them out there.
"It's funny because I made them look at butts!"
By and large, receiving unsolicited porn is a minor inconvenience in your day. You open an email, and then either make a face and delete it or kind of nod a little and save the files for later. Such was not the case for Andrew Holland. A friend sent him a video of a woman having sex with a tiger. As a result, Holland was arrested and put on bail for six months. When word got out, he was harassed so mercilessly by online vigilantes that he suffered a near-fatal heart attack. He lost his job, and was forced out of town by the relentless harassment, which included physical beatings. He was also labelled a pedophile by people who just started to make guesses as to what he was charged with, which caused him to lose contact with his daughter for over a year. And to this, you might think "Good, that's what you get for having sick porn on your computer." Except he didn't.
