This is brought up a bunch, but I’m kind of sceptical about this.

Although only a small percent post, I believe those users are largely interchangeable and replaceable. This isn’t twitter - apart from a few exceptions, there are not personalities on Reddit that people would feel the loss of. All the big/main subreddits are all pretty low-effort content, just reposting memes and videos from elsewhere.

Mods maintaining the subreddits are the real ‘power users’ who would impact the site if they left.
