This book draws together both primary and secondary empirical research and existing literature to examine transgressive subcultural activities and engagement in digital social spaces (DSS). The book addresses four objectives:1. To understand how young peoples subcultures arise online and they are constructed and experienced in DSS2. To understand how and why DSS matter to young people3. To understand if any DSS controls exist in these online spaces and4. To understand how identity locations such as social class, gender and ethnicity and/or their intersections shape young peoples engagement and behaviour(s) in DSS. In addressing these objectives with a focus on European contributions, the text provides a holistic understanding of the purpose of digital social spaces in shaping young peoples identities and self-perceptions. It will be of interest to postgraduate students, secondary school teachers, lecturers and scholars in education, sociology, youth studies and technology.
