Australia has introduced a world-first social media ban for children under 16, starting Wednesday. Riley Allen, a 15-year-old from a remote sheep ranch, is concerned about staying in touch with friends. Platforms like Facebook and TikTok face hefty fines if they don't comply. Riley's mother, a teacher, supports the ban but acknowledges kids might find ways around it. Another 15-year-old, Noah Jones, is challenging the law in court, arguing it limits freedom of communication. Critics warn the ban could push kids to less regulated platforms. The case will be heard next year.
