"We come together as one...and hope for solidarity to live on": On designing technologies for activism and the commemoration of lost lives

On the International Day to End Violence Against Sex Workers (IDEVASW), sex worker rights advocates and support services commemorate lives lost due to violence. In this paper we describe and reflect on a Feminist Participatory Action Research project that supported the activities of IDEVASW over two years in North East England. Working alongside a charity that provides services to women who are sex workers or have experienced sexual exploitation, we co-organised the first activist march on the day. As researchers and service providers, we present detailed reflections on the use of digital technologies during the public activist march, a private service for commemoration, and the development of a semi-public archive to collect experiences of the day. We develop three implications for the design of digital technologies for activism and the commemoration of lost lives: as catalysts for reflection and opportunities to layer experience.
