My identity comment was tied to Mullvad itself. They don’t require any identifying information when signing up. For the kind of protection you’re talking about, yeah you’re gonna have to go further than just a VPN. Their fingerprinting capabilities are ridiculous.
Oh, yup! Mullivad is pretty badass like that. You can mail them cash in an envelope and they'll add it to your subscription. Haha. Almost unheard of in today's society.
