Build 'MindGuardian'—a decentralized, AI-driven content moderation and mental health monitoring platform for minors on social media. The platform would: 1) Use federated learning to analyze posts/interactions in real-time without storing user data; 2) Provide customizable 'Safety Profiles' for different age groups (e.g., '13-15: No self-harm content'); 3) Integrate with school systems to auto-flag concerning patterns (e.g., 'User X posted 12x about suicide this week'); 4) Offer 'Digital Wellbeing Dashboards' for parents with real-time alerts (e.g., 'Your child’s sentiment score dropped 40% today'); 5) Auto-generate 'Mental Health Reports' for pediatricians and counselors.

Social media bans for minors create a vacuum for safe, compliant alternatives. Parents and schools lack tools to monitor digital wellbeing without invading privacy. The friction includes: 1) Psychological harm from abrupt account shutdowns; 2) Lack of trustworthy alternatives; 3) Operational gaps for schools and NGOs; 4) Risk of minors migrating to unregulated platforms.
