Why VPNs Get Revoked or Blacklisted
When using a VPN alongside WSF (whysoooofurious) custom DNS for sideloading apps or accessing region-restricted content, your device can be tracked or flagged. This is especially true if your VPN is leaking DNS queries or if you’re using default DNS servers that log traffic.
The solution? Use a madNS VPN setting that includes custom DNS servers and DNS-over-HTTPS (DoH) for full protection, privacy, and revocation resistance.
What Is madNS and Why You Need It

madNS is a smart DNS configuration system designed to work hand-in-hand with VPNs and WSF (whysoooofurious) to block revokes, stop app updates, and block ads or malicious scripts.
By changing your VPN’s DNS settings to the ones listed below, you add a powerful layer of protection and privacy, drastically reducing the risk of getting blacklisted or revoked while using third-party services or sideloaded apps.
