This isn’t a platform it’s a protocol. Are you sure there is no client that offers what you want. Most clients offer mute lists, most relays offer filters.

If what you want doesn’t exist and you think there is a demand for it, suggest it to the open source community or better still code it yourself. If you can’t code, but see a compelling feature, then maybe that’s an opportunity to learn to code.

There are no overlords here, there is nobody telling you what you can or cannot do. There is nobody to blame and there is nobody to praise.
