Aamzingly, I don't even get this page. I just see the default "this page is not available" from my browser. I'm with Vodafone, and I wonder if it is legal to pretend a site doesn't exist without notifying me.

Pretty sure it's DNS level block. So just using private DNS would be enough, no need for full blown VPN. It's just that VPNs also usually use their own DNS instead of the ISPs.

I recommend NextDNS or similar to bypass those DNS blocks and also block ads at a very deep level that works ok mobile and even inside apps.

I'd rather complain why somebody decides for me where what websites I'm allowed to open
