Summary
The UK has expanded its Online Safety Act to require digital platforms to implement preemptive scanning and blocking of user content before it can be seen.

· 4 pulledA major expansion of the UK's Online Safety Act (OSA) has taken effect, legally obliging digital platforms to deploy surveillance-style systems that scan, detect, and block user content before it can be seen.
The government's new Online Safety Act 2023 (Priority Offenses) (Amendment) Regulations 2025, which came into force on January 8, 2026, designates 'cyberflashing' and 'encouraging or assisting serious self-harm' as priority offenses, categories that trigger the strictest compliance duties under the OSA.

The system demands machines make moral calls in real time.
