This study drew on interviews with elementary school children (aged 8-12), parents and teachers to explore whether and how children name online infringements of their rights and mobilize their rights when they experience such infringements. The findings revealed distinctions between rights infringements external to children's social world and infringements internal to this world that are intertwined with children's close relationships. Naming internal infringements proved more complex, particularly when the injuries were masked as pranks or conducted between siblings. The distinction between internal and external rights infringements was also apparent in children's mobilization of their online rights.
