If the public list has an entry for you even though you respond with empty answers, that list is broken and you should send them a complaint.

For optimal control over the behaviour of your recursor, please do NOT run it behind an authoritative server. Once your recursor is running independently, you can use the allow-from* settings in recursor.conf, or even packet level filtering (like iptables) to make sure you don’t respond to queries.
