This article details the making of community and bodies in online environments, specifically the online pro-anorexia community. Building community among members of these groups is particularly fraught because tensions over claims to authenticity permeate these groups. Because these are embodied practices and online spaces are presumably disembodied, participants constantly grapple with authenticity, largely through the threat of the ‘wannarexic’. Participants manage these tensions through engaging in group rituals and deploying individual tools that attempt to make the body evident online. This article documents the way in which tensions around authenticity and embodied practices are managed through treatment of the wannarexic.
