This chapter explores the online posthumous memories of Zyzz-an amateur bodybuilder and social media celebrity who died of a heart attack at the age of 22. It compares how memories of Zyzz are distributed and contested across multiple platforms, including niche body-building fan sites, popular social networking sites, and other online information-sharing or discussion forums. Based on a comparative analysis of content from these platforms, the chapter reveals how memories are subject to a tension between coherence and dispersal under the conditions of distributed networks. Digital memories are persistent, replicable, scalable, and searchable; yet they do not remain stable, with digitally networked data often fragmented, incomplete, restricted or obscure. We argue that in these contexts, memories of the dead are susceptible to competing, partial, and disparate accounts, which endeavour to secure a particular view of the deceased and identify a specific legacy that the deceased leaves behind.
