Most of reddit is controlled by "powermods" who mod anywhere from dozens to hundreds of subreddits. They collect them for clout and don't give the slightest damn about their communities, don't participate in them, don't have time to even spend time reading them and getting a feel for them, etc. They're not trained or educated in community management for the betterment of said community.
Nobody has the sort of free time to spend moderating an active community, especially unpaid - and therefore they must be getting paid by someone other than reddit. I'm convinced that a large number of subreddits are moderated by accounts that are controlled, directly or indirectly, by advertising, PR, and reputation management firms - and government agencies, ranging from intelligence to "PR." Either directly, or via payoffs to promote or suppress certain subjects, topics, and types of posts.
I think there's a reason Ghislaine Maxwell - whose father was an intelligence agent - was a reddit powermod.
