Digital media technologies have enabled some LGBTQ individuals and communities to successfully organize for basic rights and justice. But these technologies can also present risks, such as online and in-person harassment and assault, and unsettled standards of privacy and consent. Justin Ellis provides new insights on LGBTQ identity formation through social media networks and platform biometrics. Drawing on debate over gender, procreation, religion, nationalism and tech-regulation, he considers the effects of surveillance technologies on LGBTQ agency. In doing so, he brings an interdisciplinary 'digiqueer' perspective to negotiations of LGBTQ identity through case studies of digital harms from case law, parliamentary debates, social and mainstream media and LGBTQ-tech advocacy.
