How is social media changing contemporary understandings of crime and injustice, and what contribution can it make to justice-seeking? Abuse on social media often involves betrayals of trust and invasions of privacy that range from the public circulation of intimate photographs to mass campaigns of public abuse and harassment using platforms such as Facebook, Twitter, 8chan and Reddit - forms of abuse that disproportionately target women and children. Crime, Justice and Social Media argues that online abuse is not discontinuous with established patterns of inequality but rather intersects with and amplifies them. Embedded within social media platforms are inducements to abuse and harass other users who are rarely provided with the tools to protect themselves or interrupt the abuse of others. There is a relationship between the values that shape the technological design and administration of social media, and those that inform the use of abuse and harassment to exclude and marginalise diverse participants in public life. Drawing on original qualitative research, this book is essential reading for students and scholars in the fields of cyber-crime, media and crime, cultural criminology, and gender and crime.
