Technologies and digital infrastructures can provide new opportunities for charities to rethink organizational control or potentials for justice. Furthermore, technologies can themselves generate new infrastructure to challenge existing structures. In order for newly adopted technologies to be useful for service delivery and not to simply reinforce existing power imbalances to amplify exclusion, they need to be embedded in the service, to follow “just sustainabilities” where attention is drawn to systemic rather than individual concerns, and be accessible for all. National Ugly Mugs (NUM) is a charity whose aim is to end violence against sex workers. They do this by providing access to justice and protection for sex workers in the UK through a digitally facilitated peer-alerting system, training police and other service providers, and through consensual sharing of intelligence with police forces. This chapter aims to look beyond digital technologies that are employed in sex work support services as “silver bullets” to solving complex socio-cultural, socio-ethical, and socio-technical problems.
