4Chan is crazy...The website has seen a lot of press, and most of it bad. It's one of the only places online that's legal, BUT has practically no rules.
You can say whatever you want without punishment. But there's one imageboard in particular that's the worst one of all. 4Chan's /B/Board. 4Chan is also filled with trolls. LOTS...of trolls. And some of them are even criminals.
And as we'll see in the video, 4Chan seems to welcome these people with open arms. As we get further into the documentary, things are gonna get insane exploring the dark world of 4Chan.
