Yes, I do get it...yet I still believe (STRONGLY) that we need to develop tools that let USERS control and filter their own content--and to not rely on someone else (e.g., relay operators) to do it.

Frankly, the functionality to "focus" a user's feed is really missing from Nostr currently...developing such a framework would help to solve both problems.

Decentralization is the primary core tenet of Nostr--and any "filtering" should be decentralized as well.
