alt Hacker NewsThe only viable way to even get most of them is to shut down internet access entirely. It's not a realistic solution, unlike blocking a few well known IP ranges belonging to a large corp like Cloudflare.
And even if you managed to get them all beforehand, some VPN providers will adapt and keep some servers in reserve, putting them online just as you managed to block the previous ones. Getting around internet censorship is a large chunk of their business, and some are really good at it.
You don’t really need to block all, you just need to annoy the users enough that paying is easier. And I think there are enough games to use up the IP reserve pretty quickly and getting new ones every time is pretty annoying.
