In the lawsuit, 4chan and Kiwi Farms claim that threats and fines they have received from Ofcom constitute foreign judgments that would restrict speech under U.S. law.Both entities say in the lawsuit that they are wholly based in the U.S. and that they do not have any operations in the United Kingdom and are therefore not subject to local laws. Ofcoms attempts to fine and block 4chan and Kiwi Farms, and the lawsuit against Ofcom, highlight the messiness involved with trying to restrict access to specific websites or to force companies to comply with age verification laws.The lawsuit calls Ofcom an industry-funded global censorship bureau.Ofcoms ambitions are to regulate Internet communications for the entire world, regardless of where these websites are based or whether they have any connection to the UK, the lawsuit states. On its website, Ofcom states that over 100,000 online services are likely to be in scope of the Online Safety Actfrom the largest social media platforms to the smallest community forum.Both 4chan and Kiwi Farms are notorious online communities that are infamous for their largely anything-goes attitude. Users of both forums have been tied to various doxing and harassment campaigns over the years. Still, they have now become the entities fighting the hardest against the UKs disastrous Online Safety Act, which requires websites and social media platforms to perform invasive age verification checks on their users, which often requires people to upload an ID or otherwise give away their personal information in order to access large portions of the internet. Sites that do not comply are subject to huge fines, regardless of where they are based. The law has resulted in an internet where users need to provide scans of their faces in order to access, for example, certain music videos on Spotify.The Electronic Frontier Foundation has said the Online Safety Act is a threat to the privacy of users, restricts free expression by arbitrating speech online, exposes users to algorithmic discrimination through face checks, and leaves millions of people without a personal device or form of ID excluded from accessing the internet.Ofcom began investigating 4chan over alleged violations of the Online Safety Act in June. On August 13, it announced a provisional decision and stated that 4chan had contravened its duties and then began to charge the site a penalty of 20,000 (roughly $26,000) a day. Kiwi Farms has also been threatened with fines, the lawsuit states."American citizens do not surrender our constitutional rights just because Ofcom sends us an e-mail. In the face of these foreign demands, our clients have bravely chosen to assert their constitutional rights," Preston Byrne, one of the lawyers representing 4chan and Kiwi Farms, told 404 Media.Ofcom did not immediately respond to 404 Medias request for comment.
