Communities are the bedrock of society - physical spaces where residents share a collective purpose and common goals. But the internet has given rise to a new kind of community where lies and hate can flourish. In this episode meet a would-be utopia in Spain where civic life is managed on Twitter; a teacher who becomes the target of a digital lynch mob; and the father of a school shooting victim who must prove to the internet that his son existed.
