Based on ethnographic fieldwork including video recordings, this study examines how pre-teen girls, in everyday peer interaction, deal with controversial issues on a social media network. Drawing on a multimodal interactional approach, we analyze the situated affective and collaborative embodied work through which a peer group unravels and remedies problematic online behaviors (cheating, scamming,stealing). The results show how the girls affectively align themselves to deal with online risks in ways that demand different social media skills as well as networks of supportive peers. The girls agentively draw upon the affordances (texting, images, social norms) of the social media network as well as their expertise and collective knowledge of similar online events. The creative power of the peer group plays an important role, in terms of how the girls nourish their peer culture while building mutual trust and collaborative competencies for interpreting and anticipating risky practices in their lives with peers.
