Prior work has established that privacy on networked publics, such as social media, is complex, requiring users to navigate not only the technical affordances on the platform but also interpersonal relationships and social norms. We investigate how teenagers think about privacy on the popular image-sharing platform, Instagram. We draw on interviews with 12 teenagers (ages 13-18) and an online survey to gain a better understanding how the teenagers configure privacy on the popular image-sharing platform Instagram and why they make these privacy decisions. Finally, based on our findings, we provide design and policy recommendations towards the design of better privacy controls for promoting teenage safety online.
