I used to run a public TLS DNS server that would do some hardcore ad/tracking blocking. I shut it down when I switched myself, friends and family to a private Tailscale network with VPN on the exit nodes.
It was a little janky to manage but I still have the files laying around; my point is I could turn it back on. Since it’s DNS-based it applies to all websites and apps running on your devices, and with TLS it’s also encrypted so your ISP wouldn’t be able to track your DNS requests. You would however be trusting me, a random stranger with your queries.
