That's something I've been grappling with recently, and the solution I landed on as "good enough" (though far from perfect) is to have a community where the ability to post and interact is closed, but the ability to view the content is open. Some subreddits have tried a variation of this, such as the Economics subreddit granting a "Bureau Member" flair for individuals who have proven their knowledge of economics in long form posts, but without taking it farther than just extra flair. There's no weekly threads for Bureau Members only to post, or anything like that. The issue then becomes how do you set up a judging body that determines the criteria for who is allowed to interact, and prevent that body from being co-opted in some way. Not an easy task, especially for a social media company where there's absolutely perverse incentives at play.
