UK Online Safety Act enforcement begins with Ofcom issuing first illegal content notices

Ofcom, the United Kingdom communications regulator, has issued its first formal notices to social media platforms under the Online Safety Act 2023, requiring them to demonstrate compliance with illegal content duties including child sexual abuse material and child sexual exploitation. The notices mark the beginning of active enforcement of the landmark legislation and require platforms to provide evidence of their systems and processes for identifying, removing and preventing the spread of illegal material.

When detection operates at the point of contact rather than after publication, the regulatory obligation shifts from reactive removal to upstream prevention. Real-time pattern analysis that identifies coercion, escalation and predatory targeting in direct messages before harm crystallises addresses the illegal-content duty at source, without requiring platforms to retain or review message content at scale. Guardii's anti-grooming and anti-CSAM detection modules flag hostile or exploitative conversation patterns as they develop across Instagram, Snapchat, Discord, Roblox and other services, reporting risk rather than reading every exchange, and enabling platforms to meet their legal duty to protect children while preserving the confidentiality of private communications.
