Graffiti is widely used in social movements globally, yet media and communication research disproportionately focus on the role of social and new media technologies in protest movements. In this paper I ask why university students – a tech-savvy generation – resorted to graffiti and why campus graffiti were not widely circulated on social media during the Hong Kong anti-Extradition Law Amendment Bill (ELAB) protests. I argue that graffiti enables dispersed resistance and is one way to mobilize, voice dissent, and preserve memory in an increasingly surveilled and evolving repressive media environment. I pursue this argument by analyzing graffiti photographed on university campuses during the anti-ELAB protests. Situating graffiti within protest culture in Hong Kong, I conclude that graffiti are not always circulated on digital/social media to reach a broader audience. In times of crises, not reaching a wider audience is a manifestation of dispersed resistance in a hybrid media environment.
