It's a very interesting situation. Personally, I would love to learn about the experience and knowledge each user has developed.
I would leave these questions:

In your opinion, what would be the characteristics of the model user on the platform?

To what extent do you think the abuse of an investor's content should be allowed?

What characteristics and skills should users have to create a community and manage a reliable and successful community account?

I would assess the level of seriousness and support that each participant can provide.
