does this mean the UK will block 4chan in the UK? if the defense is jurisdictional then 4chan can continue to serve US users, but there would be no recourse if the UK blocks it in their jurisdiction
What Ofcom wants next is to make VPNs illegal.
https://www.blocked.org.uk/site/http://www.4chan.org suggests the latter to me, but the checks aren't very recent
I think the Spain-Cloudflare case does IP level blocks and it has a lot of side effect damage, but if I recall they do IP-block level blocking because the vendor, cloudflare, provides header/envelope encryption and pooling, so the Spanish courts considers it legal to block the whole service even, alleging that they are not collaborating with court orders, they just choose not to block the whole provider to reduce the collateral damage, even if they consider they have jurisdiction to block all of CF
Beyond that, it is just madness to try to control the US company or fine it. Going beyond this duty shows that not all biscuits are present at the afternoon tea.
It's not like Facebook, or anyone's personal life or business, depends on 4chan.
I think OFCOM themselves recognize the problem with trying to ban VPNs, but extremely dim MPs and extremely angry newspapers (who are the underlying enemies of free speech here) don't.
