Again, several people explained to you that your assessment is wrong,
that you are delusional and there is no such thing as "Google Hidden
Internet". (I can resolve the name just fine, and I use zero Google
service.)

people will refuse to reply to you.

As was explained to you by several persons, BIND is not at fault
here. The problem is that YOU decided to forward to apparently broken
resolvers.
