The UK government plans to prohibit social media use for children under 16, targeting major platforms including Snapchat, TikTok, YouTube, Instagram, Facebook, and X. The proposed ban aims to protect minors from online risks, though messaging services like WhatsApp and Signal would remain accessible. This move follows growing concerns about youth exposure to inappropriate content and social media's impact on mental health.

The restrictions extend beyond social media to include gaming sites and other online services. Platforms would face limitations on "harmful functions" such as live streaming and communication with strangers. These broader rules would apply to users under 17, creating a tiered approach to online age verification. The government hasn't specified exact implementation methods or enforcement mechanisms.

AI chatbots face additional scrutiny, with "romantic companion" chatbots banned for those under 18. Any AI chatbot offering "similar intimate functionalities" would also be restricted, including general-purpose platforms. This addresses recent concerns about AI interactions with minors.

The first regulations could take effect next spring, pending Ofcom's study on effective age verification methods. The government committed funding for Ofcom to research and enforce these measures. Implementation details remain unclear, leaving tech companies and families uncertain about compliance requirements.
