I don't know how hard this would be to develop, but perhaps a content creator discovery section. In order to not fall into the pay-to-play issues that other socials have, perhaps content creators can *join* that section and those in the pool are promoted at random.

When they appear, they can be identified by their profile and the kind(s) of content they create. Promotions can rotate daily and may either be random groupings of content creators or organized by content type (Ex: Monday promotions are three fine artists, Tuesday promotions are three photographers, etc)
