The Commission is concerned that the systems of both Facebook and Instagram, including their algorithms, may stimulate behavioural addictions in children, as well as create so-called 'rabbit-hole effects'. In addition, the Commission is also concerned about age-assurance and verification methods put in place by Meta.

Today's opening of proceedings is based on a preliminary analysis of the risk assessment report sent by Meta in September 2023, Meta's replies to the Commission's formal requests for information (on the protection of minors and the methodology of the risk assessment), publicly available reports as well as the Commission's own analysis.

The current proceedings address the following areas:

• Meta's compliance with DSA obligations on assessment and mitigation of risks caused by the design of Facebook's and Instagram's online interfaces, which may exploit the weaknesses and inexperience of minors and cause addictive behaviour, and/or reinforce so-called ‘rabbit hole' effect. Such an assessment is required to counter potential risks for the exercise of the fundamental right to the physical and mental well-being of children as well as to the respect of their rights.
• Meta's compliance with DSA requirements in relation to the mitigation measures to prevent access by minors to inappropriate content, notably age-verification tools used by Meta, which may not be reasonable, proportionate and effective.
• Meta's compliance with DSA obligations to put in place appropriate and proportionate measures to ensure a high level of privacy, safety and security for minors, particularly with regard to default privacy settings for minors as part of the design and functioning of their recommender systems.
