People think blocked domains prove privacy. They don't. Cleaner logs can hide a DNS stack that's split across browser overrides, VPN rewrites, and device settings.
This is why DNS filtering frustrates people. Login flows get weird, streaming breaks, smart home junk acts stupid, and suddenly privacy feels like punishment.
Write down five things: resolver per device, VPN drop behavior, app bypasses, IPv6 handling, and if your router enforces or just suggests. That will tell you more than another week of tweaking settings. #privacy
