4chan is openly defying British regulators by refusing to pay a £20,000 fine imposed by Ofcom under the Online Safety Act, which mandates companies to manage illegal content risks. The site's lawyers argue that the fine should not apply to them as a US-based organization, claiming it infringes on free speech rights. If 4chan continues to ignore the fine, Ofcom may take further enforcement action, including potentially blocking UK access to the site.
