Yep. Relays know everything about what you are asking and what they are returning, regardless of how many tors for vpns you use.

Correct me if I'm wrong, but doesn't the use of a proxy provide some anonymity? Sure, relays can see everything associated to an IP, but unless the client does something to identify itself (like signing an event, AUTH, etc...), it's just data in aggregate. Can't associate it to a specific npub.
