Digital Services Act (EU DSA)
Comprehensive EU regulation banning targeted ads to minors and requiring risk assessments for algorithmic systems.
What EU DSA Requires
Key provisions of Digital Services Act
Ban on Ad Profiling of Minors
Very large online platforms are prohibited from using personal data of minors for advertising profiling. This applies to all forms of behavioral, contextual-behavioral, and interest-based ad targeting directed at users known to be under 18.
Systemic Risk Assessments
Platforms must conduct regular risk assessments evaluating the impact of their algorithmic systems on minors, including risks to mental health, exploitation, and exposure to harmful content. Risk reports must be submitted to the relevant Digital Services Coordinator.
Age-Appropriate Terms and Design
Terms of service and privacy policies directed at minors must be written in clear, age-appropriate language. Interface design must account for the developmental needs of young users and avoid manipulative patterns.
Recommender System Transparency
Users, including minors, must be offered at least one recommender system option that is not based on personal data profiling. Platforms must clearly explain how their recommendation algorithms work and provide opt-out mechanisms.
Transparency Reporting
Very large platforms must publish transparency reports at least annually detailing content moderation decisions, algorithmic system audits, risk assessments, and the measures taken to protect minors on the platform.
Fines up to 6% of Global Revenue
Non-compliant platforms face fines of up to 6% of annual global turnover. The European Commission and national Digital Services Coordinators share enforcement authority, with escalating penalties for repeated violations.
