> Wouldn't this mean that the Act only applies to services explicitly design/targeting UK users/visitors? Clearly not considering that there's nothing in 4chan that would make it explicitly targeted towards the UK. Unless Ofcom is saying something and doing the opposite.
4chan does have very minor explicit support for UK users; on some boards it puts a UK flag on their post (as it does with all other countries and territories.) It could perhaps be argued that this constitutes the site being consciously designed with UK users in mind. Hardly matters though, there's nothing the UK can do about it. They aren't a superpower anymore and it's time for them to realize it.
Presumably if the latter, one may express their support of the flag of their choice; or indicate their heritage; or any number of other reasons.
If the former, and considering the existence of a .uk TLD, they probably are considered to be “targeting” that market.
