Core Viewpoint - France is preparing to implement strict restrictions on social media use for minors, aiming to establish a minimum age for social media usage, following Australia's lead in banning access for individuals under 16 years old [1][2]. Legislative Measures - The French government has completed a legislative draft that proposes two key measures: banning social media use for individuals under 15 years old and prohibiting high school students from using mobile phones on school premises [1]. - This legislation is expected to be submitted to parliament for discussion after the New Year, with a target implementation date of September 2026 [1]. Rationale Behind the Legislation - The French government views excessive social media use among youth as a systemic social risk, linking it to increased exposure to inappropriate content, cyberbullying, anxiety, and sleep disorders, which can negatively impact academic performance and mental health [2]. - President Macron has emphasized the negative correlation between screen time and academic performance, likening social media to "high-performance racing cars" that pose risks when minors lack self-control [2]. Compatibility with EU Regulations - The French government aims to ensure that the proposed ban aligns with the EU legal framework, particularly the EU Digital Services Act, which may provide a replicable regulatory model for other European countries [2]. - Countries like Denmark and Norway are reportedly considering similar restrictions, indicating a growing consensus on establishing a minimum social media usage age in Europe [2]. Implementation Challenges - The successful implementation of the ban faces challenges, including effective age verification, defining platform responsibilities, and preventing users from circumventing restrictions through technical means [3].

Core Viewpoint - The increasing use of social media among teenagers presents both opportunities for engagement and significant challenges related to mental health, privacy, and exposure to harmful content, prompting calls for regulatory measures and educational initiatives across various countries [1][2][3].

Group 2: Regulatory Measures in Europe - Many EU countries are implementing strict age restrictions for social media use, with most platforms prohibiting registration for children under 13, and requiring parental consent for minors [3]. - The EU's "algorithm ban" under the Digital Services Act prohibits personalized advertising to minors and automatic playback features to mitigate addiction risks [3]. - Germany is exploring AI systems to assess user age based on profile information and interactions, automatically converting accounts of identified minors to "teen accounts" with content restrictions [4]. Group 3: Australia’s Legislative Actions - Australia has enacted the 2024 Cybersecurity (Minimum Age for Social Media) Amendment, banning social media use for individuals under 16, with penalties for platforms failing to comply [6]. - The Australian government is collaborating with industry experts to ensure effective implementation of age verification technologies [6]. - The "Head Up Alliance," formed by concerned parents, supports the new legislation aimed at protecting children's mental health from social media's adverse effects [7]. Group 4: Brazil's Approach to Online Safety - In Brazil, a significant portion of teenagers openly shares personal information on social media, raising privacy concerns [8]. - Brazil's Internet Civil Framework and General Data Protection Law require parental consent for collecting minors' data, with new legislation proposed to enhance online safety measures [8][9]. - Schools in Brazil are incorporating cybersecurity education into their curricula to help teenagers recognize and manage social media risks [9].
