Just checked the list of blocked domains, and my very first try if I can open it, I got also a censorship website from the spanish government (I'm in spain, provider is DIGI) for fitgirl-repacks.site - other (mostly german) piracy sites from the list open fine.
Spain here too, Vodafone, and fitgirl-repacks.site also displays "ESTÁ USTED INTENTANDO ACCEDER A UN SITIO WEB ILEGAL" if I accept the (obviously) mismatched certificate they're using.
Surprisingly, thepiratebay.org is available for me though without issues. My previous ISPs here (Movistar, Orange, Jazztel) were all blocking thepiratebay.org
Seems to be pretty hit/miss what exact domains various ISPs block here. I would have imagined the police/courts serve like a centralized .txt file (simplified) the ISPs just fetch once a day or whatever, but seems to be way less organized than that, for better or worse.
just set my DNS to 1.1.1.1 and am no longer bothered with that censorship.
But now you are telling CloudFlare about every domain you visit.
You are right. Found out there is also DNS4EU with a bit more privacy-friendly orientation. How much they log, well, unless they get audited, I won't know.
Simply use https://quad9.net/ 9.9.9.9 instead.
