I'm a bit confused by comments on this topic. Do sovereign countries not have the right anymore to decide their own laws and issue punishment when they're not followed?
Like, they obviously can't enforce these fines. This article says as much. The fines can't be enforced, but if 4chan ignores them, that opens the door for other measures like delisting the site from search engines or blocking access to it from the UK (these two examples are taken from the article). Which are fair measures imo.
Like, to the people saying UK can't do laws which apply to services which are merely accessible in the UK and have no physical presence there, do you also apply this logic to the GDPR, which works the same way? The US has these laws too, like COPPA iirc. It's not really something the UK came up with, it's a bit of a standard with laws like this as far as I know.
