Yes, just like is says in the post. But i will emphasize that metadata is not your friend, when combined with all the other activities visible to all relays, it can reveal much, especially if you are not using a VPN. 3 letter agencies can and regularly do find people based on metadata alone. Malicious relays aside, all it takes is fov pressure to make relay runners hand over what they have. Nostr is not a "no logs" kinda protocol, so it's important for users to reduce the data they provide by themselves.
