Social media complicates relations between individuals, institutions, businesses and police, by acting as a platform where all these groups converge. This book looks at the rise of surveillance practices on social media, using Facebook as a case study. Drawing on in-depth interviews with different types of users, it underscores new practices, strategies, concerns and risks that are a direct consequence of living on social media. Recent scholarship has considered social change stemming from social media (Miller 2011, Turkle 2011). These works point out the way that social relations are transformed by virtue of being mediated on platforms like Facebook. Issues of privacy, exposure and visibility clearly matter in these studies. This book follows from these concerns by concentrating on the process by which users manage their personal information on social media, while taking advantage of the information that others put up.
