The kind problem is generic and applies to all notes.

Kind 1 will always sadly be a dumping ground for bots, automating, testing, random content, advertising, etc. Because it’s the easiest and widest audience.

If you want a dating app.. you don’t need kind 1. If you want only fans, you don’t need kind 1 - keep a non-explicit kind 1 account if you like - which is how Twitter is often used today in addition to an adult account elsewhere.

I’m not suggesting a single kind either. It depends on the use case.

Again. Separation at a relay level makes a lot of sense and makes almost all this simple and easy today without changes. Relays are dumb and easy to stand up - you are still censorship resistant with this approach. It’s not banishing the people or content. It’s just centralising the communities.

Another feature you may wish to push for is ability to select which relays to publish to. And multiple accounts in a single app. Both useful for this. This will come anyway.. but it’s valuable for what you want to achieve.
