UK Enforces Proactive Block on Unsolicited Nude Images Under Online Safety Act

Ofcom will now consult on updated codes of practice to set out the specific safeguards platforms must implement.

Overview

  • Cyberflashing is now a priority offence, requiring social media and dating platforms to detect and prevent unsolicited nude images before users see them.
  • The law took effect on 8 January, shifting duties from reactive takedowns to proactive technical and policy measures across major services.
  • Non‑compliance can trigger fines of up to 10% of qualifying worldwide revenue or lead to services being blocked in the UK.
  • Expected safeguards include automated detection systems, image‑blurring tools, stricter content policies, and enhanced moderation workflows.
  • Bumble welcomed the change and highlighted its AI‑based Private Detector as a model, while Technology Secretary Liz Kendall pressed X over Grok‑linked sexualised deepfakes and Ofcom engaged the platform on its legal duties.
