Which is why Mullvad used to not allow auto-billing if you had portforwarding. If you wanted to use portforwarding, which Mullvad had for years, you needed to pay in advance for how much you wanted to use it. They didn’t need to keep any of your information on file, including payment stuff. Just that a particular account is paid up until a certain date. Linking a port to an account ID is possible, but there is nothing that needs to be kept about the owner of an account id either. So even LE can’t really do much with that information.
