The organisers will openly debate with participants the pros and cons of policy interventions proposed to address the negative effects of social media on children. The debate will focus on how to address: Manipulative design (e.g. infinite scrolling), and Harmful content (e.g., suicidal or extremist posts) Discussions will explore whether and how harms can be effectively and proportionately addressed through policy, such as outcome-based rules, prescriptive design standards, industry-wide norms or outright bans. Context will be provided through a brief outline of existing and upcoming legislation (e.g., GDPR, DSA, AI Act, Digital Fairness Act). The aim is to surface the technical, societal and regulatory challenges and opportunities of intervening in social media design and business models, while generating ideas to advance the current debate. The three organisers - a privacy engineer, an human computer interaction scientist, and a regulatory expert— will guide the debate on both technical and policy levels.
