That doesn’t matter. I had three users plus me. And those three were/are pseudo users for WordPresses and named by sites. And I created new content, as I still do.
That wasn’t an issue as it wasn’t on WordPress world. There is two things people just don’t see neither care: urls and writer’s name. But they see really fast two other things: if a content is created for ads, and if a writing user is fake.
But that is academic for you. There isn’t such plugin/component. So if you choose that road you have to code by yourself of act manually.
