Meta has introduced "Teen Accounts" on Facebook and Messenger, automatically enrolling users under 18 to enhance their safety. Key restrictions include limiting messages to individuals teens follow or have interacted with, ensuring only friends can view and respond to their stories. Additionally, teens will receive notifications to log off after one hour of screen time, and apps will switch to "quiet mode" at night. This initiative follows increased calls for safety measures amid concerns about social media's impact on mental health. Critics express skepticism about the effectiveness of these features, noting previous claims by Meta about implementing similar safety measures.
