The alternative to that is either:
1. UK blocks cloudflare (unlikely, come on now)
2. UK gives cloudflare a pass (fairly common)
3. Somewhere in-between. Maybe UK cares about highly visible people behind cloudflare like 4Chan but not others.
no, they just drop customers when people complain that they host legal content they happen to disagree with (KF).
I think if you want cloudflare to host your site, don't kill people with your site. That seems fair IMO.
If you want to talk about content that objectively breaks laws... 8chan hosts monkey torture videos.
