The social media landscape is changing. The 'public forum' is now filled with citizens selling products, promoting services, charging for subscriptions, and sometimes seeking attention in ways which may not be socially desirable. We ask: How can a space that is becoming increasingly commercialised, monetised, and is a source of income for many nevertheless be fair? Departing from this foundational question, this symposium pursues many more granular ones, each anchored in whether and how the rights of users in social media spaces can be strengthened vis-à-vis dominant platforms via social media contracts.
