4chan will probably end up paying the fine and engaging immediately when it is blocked in the UK as it will result in their top line getting hit. There is also an option of seizing the assets belonging to the company (not necessarily just in the the UK although probably not in the USA). You are deluded if you think otherwise.
It will end up the same as tech giants fines. They will shout, moan and pay.
I especially like this hysterical statement:
The statement added the US federal authorities had been “briefed” on the matter, adding that the Ofcom investigation was part of an “illegal campaign of harassment against American technology firms”.
