Adult content
In effectOnline Safety Act 2023 (Royal Assent Oct 2023). Since July 25, 2025, services hosting pornography or content harmful to children must use "highly effective age assurance" -- typically photo-ID upload, credit-card check, facial-age estimation, mobile-network checks or open banking -- to keep under-18s out. Ofcom had opened 90+ investigations by February 2026 and has escalated steadily: AVS Group fined 1 million pounds (plus 50,000 for ignoring information requests) in December 2025 over 18 adult sites; Kick Online Entertainment fined 800,000 pounds in February 2026 for 34 sites drawing 9 million monthly UK visitors; an AI 'nudification' site fined 55,000 pounds; and 4chan hit with a 450,000-pound penalty plus daily fines after refusing to engage at all. Enforcement has widened past adult sites to generative AI, with investigations into X (over the Grok chatbot) and the AI service Joi.com opened in January 2026. Maximum penalty is 18 million pounds or 10% of global turnover, and Ofcom can seek court orders forcing ISPs to block a site outright. Some platforms left instead: Aylo blocked new UK users from Pornhub, YouPorn and RedTube on February 2, 2026, calling the regime a failure, before partially returning in May 2026 for users verified through Apple's new device-based age check.
