If 4chan continues to ignore Ofcom, the forum could be blocked in the UK. And 4chan could face even bigger fines totaling about $23 million or 10 percent of 4chan’s worldwide turnover, whichever is higher. 4chan also faces potential arrest and/or “imprisonment for a term of up to two years,” the lawsuit said.
Not who you replied to, but: there is no legal, ethical, or moral, requirement for a business of one country to comply with the laws of another. If there was, all business would be beholden to the most overbearing government on any one subject. And just to specifically state it before it’s brought up, being tied into the international banking system doesn’t change that; if a state doesn’t want its citizenry doing business with a particular entity, it’s on them to stop it on their side or come to an agreement with the other’s government. Which does happen, especially with the conglomerate hegemony of components of the international banking system, but naturally that means that the only time any entity of a state is forced to comply with the laws of another is when their home-state demands it, which ultimately isn’t the laws of the other.
Their payment processor is operating in the UK though. 4chan isn’t refusing money from UK residents. It is accepting their payments.
