The UK online safety regulator Ofcom has fined the US messaging platform 4Chan £520,000 for failing to comply with various aspects of the Online Safety Act, including not implementing age checks to prevent children from accessing pornography. 4Chan has refused to pay the fine, with its lawyer responding with an AI-generated cartoon image of a hamster. The fine also includes penalties for failing to assess the risk of illegal material being published and not protecting users from criminal content. Ofcom has stated that companies must comply with UK online safety laws, regardless of their base of operations.
