Teenagers are avid users of Discord, a fast-growing platform for synchronous communication where they often interact with strangers. Because Discord combines private DMs, semi-private voice channels, and public servers in one place, it creates a hybrid environment that can produce complex—and underexplored—safety risks for teenagers. Drawing on 16 interviews with teenage Discord users, this study examines their strategies for navigating risky social interactions in the platform. Our findings reveal that when teenagers encounter risks during social interactions, they exercise vigilance by evaluating suspicious interactions before forming friendships, using safety tools, and engaging in controlled risk-taking to safeguard their privacy and security. At the community level, they mitigate risks through selective participation in servers, a practice supported by vigilant governance structures. We discuss how vigilance enables teenagers to act during risky encounters to protect themselves, advancing understanding of teenagers’ agency in risk navigation and informing teen-centered designs for safer online environments.

With the development of consumer surveillance technologies, monitoring has become increasingly accessible and woven into family life. Prior work has examined parents’ attitudes, privacy concerns, and selected uses of surveillance technologies like smart cameras and location-tracking apps, but offers limited accounts of how parents, as surveillants, configure and experience these technologies themselves in daily parenting. We address this gap by focusing on baby monitoring technologies (BMTs) as a high-salience context during a sensitive stage of family life. Using inductive thematic analysis of Reddit discussions, we examine how parents engage with BMTs in practice. Our findings revealed how parents actively assemble and configure BMTs, navigate and manage their emotions through them, negotiate privacy frictions and boundaries, and safeguard security in their use of such technologies within parenting and caregiving. We conclude by discussing implications for surveillance research and design for monitoring technologies in care.

Gaming is a meaningful part of children’s lives, yet its safety has drawn increasing concerns from scholars and the public. On platforms like Roblox, children may encounter extremist roleplay, scams, or virtual rape. Prior research has emphasized technical interventions that address risks after they occur and ethical frameworks for game design, but children’s perspectives on safety design remain missing. To address this gap, we conducted a cooperative inquiry study to co-design safety mechanisms with 22 children aged 7–12. Children proposed designs emphasizing transparent information about games and purchases, community accountability through reporting and reviews, player empowerment to manage social boundaries and engagement, and age-appropriate game navigation. Our findings extend safety-by-design research by foregrounding children’s perspectives, showing how they envision safety mechanisms across both game and platform design, while enjoying safe play through risk exposure, allocating trust, and balancing platform support with agency.

Computer-supported cooperative work (CSCW) researchers have studied how teenagers experience safety risks such as cyberbullying and scam, but little attention has been paid to gambling. While teenagers’ access to traditional gambling, such as casinos, has been tightly regulated, internet technology has given rise to emergent forms of online gambling, which increasingly permeate teenagers’ everyday lives and exposes them to safety threats and gambling-related harm. Addressing this issue requires a deeper understanding of teenagers' risk perception of gambling, as it not only shapes individual decision-making but also influences societal behaviors and informs policies aimed at mitigating its harmful effects. To understand how teenagers perceive and deal with gambling risks, we analyzed how teenagers engaged in collective sensemaking of gambling in the r/teenagers subreddit, one of the largest online communities on Reddit for teenagers. Our findings revealed various gambling risks perceived by teenagers, the strategies they adopt to mitigate them, and the strong sense of agency they demonstrate in engaging with gambling-related content. Based on these findings, we propose gambling intervention recommendations targeting teenagers, as well as implications for platforms and policymaking.
