The extended abstract conceptualizes digital privacy as a relational, situational, and reflexive practice that adolescents actively shape in their everyday use of social media. Rather than viewing privacy as a purely technical issue, it is understood as a form of managing visibility, social relationships, and contextual information flows. Based on the Reflexive Privacy Analysis (RPA), a qualitative and multi-method research design combining interviews, group discussions, and interaction diaries, the study develops a four-part typology of adolescents’ privacy orientations. These include situationally protection-oriented adolescents, relationally negotiating actors, reflexively curating self-presenters, and critically strategic prosumers. The findings reveal that adolescents possess differentiated but unevenly distributed privacy competencies. The typology highlights the dynamic and context-dependent nature of privacy practices and provides a framework for targeted media education. It emphasizes the need to foster digital literacy as a combination of technical, social, and critical competencies in algorithmically structured environments.

Recommender systems increasingly mediate content exposure, yet little is known about how users' identity importance shape engagement with personalised versus popular content. Drawing on the SESAM model (Knobloch-Westerwick, 2015) and Social Identity Theory (Tajfel & Turner, 1979), it was predicted that dispositional and situational, induced via social exclusion, salience of social versus personal identity would drive prederence for trending over personalised content. In an online experiment (N = 209, UK, ages 18-35), participants were randomly assigned to social exclusion or inclusion conditions via the Cyberball paradigm before browsing ClipTube, a simulated YouTube-like platform featuring trending and personalised content labels. The study revealed a significant main effect of personal identity importance on overall video selection (F(1, 194) = 6.80, p = .010), but no support for the hypothesised effects of social identity importance or exclusion condition. Implications for identity-driven selective exposure on VoD platform design are discussed

This paper examines the dual role of digital dating platforms, particularly Grindr, as both infrastructures of queer connection and sites of targeted victimization. While early scholarship emphasized the emancipatory potential of digital communication, emerging evidence highlights how platform affordances such as geolocation, persistent profiles, and rapid interaction can be exploited for harassment, extortion, and violence. Drawing on interviews, case analyses, and cross-national comparisons across the United States, United Kingdom, and Australia, the study identifies patterns of app-facilitated crime, including precision targeting, rapid trust-building, and the weaponization of personal information. These harms are not incidental but are structured through the interaction of platform design, user norms, and institutional responses. The findings challenge binary narratives of digital utopia versus dystopia, arguing instead that vulnerability is systematically produced within platform environments. Addressing these risks requires proactive design interventions, stronger institutional coordination, and a critical reassessment of platform responsibility in shaping user safety.
