This book explores the discrimination encountered and propagated by individuals in online environments. The editors develop the concept of 'online othering' as a tool through which to analyze and make sense of toxic and harmful behaviors which are being created through, or perpetuated via, the use of communication-technologies such as the internet, social media, and �the internet of things'. The book problematizes the dichotomy assumed between real and virtual spaces by exploring the construction of online abuse, victims' experiences, resistance to online othering, and the policing of interpersonal cyber-crime. It explores the relationship between various socio-political institutions and experiences of online hate speech, and the extent to which forms of information-technologies facilitate, exacerbate, and/or promote the enactment of traditional offline offences (such as domestic abuse and stalking). It focuses on the construction and perpetration of online abuse through examples such as the far-right, the alt-right and Men's Rights Activists. It also explores experiences of, and resistance to, online abuse via examples such revenge porn, online abuse and misogyny, transphobia, disability hate crime, and intersectional online othering. Finally, the collection addresses the role of the police, their interventions, and the regulation and governance of virtual spaces. Contributions come from sociology; communication/media studies; psychology; criminology; political studies; information science and gender studies. This title is one of the first to explore a multitude of abuses and their relationship to information and communication technology. It develops the concept of online othering to explore and analyze online abuse and hate in various contexts; offers an interdisciplinary analysis of the online cultures which engage in forms of online othering and abuse; presents victims' experiences; and informs the future regulation and policing of online hate and abuse.
