Web forum Kiwifarms said it also received a letter from Ofcom.
The platform is now blocking users in the UK because of the legislation.
British users are now greeted with a message:
“You are accessing this website from the United Kingdom. This is not a good idea. The letter states the UK asserts authority over any website that has a ’significant number of United Kingdom users’. This ambiguous metric could include any site on the Internet and specifically takes aim at the people using a website instead of the website itself.”
The unsigned message added that the situation in the UK is “now so dire I fear for the safety of any user connecting to the Internet from the country.”
The law has already affected dozens of smaller UK websites, from forums for cyclists, hobbyists, and hamster owners, to those supporting divorced fathers.
The regulatory pressure and the many rules have caused many of them to shut down, despite some operating for decades.
