UK Fines 4chan Under New Online Safety Law

- Ofcom fined 4chan £20,000 for failing to submit risk data on illegal content, marking the first penalty under Britain’s Online Safety Act.
First Enforcement Action Under New Law
Britain’s media regulator Ofcom has issued its first fine under the Online Safety Act, targeting U.S.-based internet forum 4chan. The £20,000 penalty was imposed after the site failed to provide requested documentation assessing the risks of illegal content on its platform. A second request concerning its global operations also went unanswered, prompting regulatory action. Ofcom stated that services refusing to cooperate with their legal duties should expect consequences.
The Online Safety Act aims to protect children and vulnerable users from harmful material circulating online. Its enforcement has sparked friction between British authorities and U.S. tech platforms, with concerns raised about its impact on free speech. Technology Minister Liz Kendall expressed full support for Ofcom’s decision, describing the fine as a warning to non-compliant services. She emphasized the importance of removing illegal content and safeguarding young users.
Legal Pushback and Escalating Penalties
In response to the enforcement, 4chan and fellow forum Kiwi Farms filed a lawsuit in the United States against Ofcom. The complaint argues that the regulator’s actions infringe on American constitutional rights, particularly freedom of expression. It also claims that Ofcom sent threatening communications to U.S.-based companies, interfering with their operations. The legal challenge reflects broader tensions over cross-border regulation of online platforms.
Ofcom announced that the fine will increase by £100 per day starting Tuesday, continuing for up to 60 days or until the requested information is submitted. Should 4chan remain unresponsive, the regulator may instruct internet service providers to block access to the site within the UK. This escalation mechanism is part of Ofcom’s broader strategy to enforce compliance. The regulator has made clear that it intends to apply the law consistently across platforms.
Broader Enforcement and Industry Response
Beyond 4chan, Ofcom reported that two file-sharing services took steps to prevent the spread of child sexual abuse material after concerns were raised. Four additional services responded by geo-blocking UK-based IP addresses to limit access from within the country. These actions suggest that some platforms are adjusting their operations in response to regulatory pressure. The regulator continues to monitor compliance and may take further action as needed.
This case marks a shift in how national regulators assert authority over foreign digital services. The Online Safety Act’s implementation is being closely watched by other jurisdictions considering similar legislation. While critics argue that such laws risk overreach, supporters view them as necessary tools to address online harms. The outcome of 4chan’s legal challenge may influence future enforcement strategies and international cooperation on digital safety.
