The moderators who run much of the site are not paid directly, but they're definitely in league.
Powermods took over reddit a long time ago. Hell, I'd go so far as to say reddit secretly promoted r/the_donald and other extremist subreddits, and had a direct hand in getting him elected.
They're really not. I got to interact with many of them during the vaxxhappened protest and I got the impression that they were largely rather timid people. I do think that Reddit management is happy with the arrangement though, because it means they can abuse the mods knowing they won't rock the boat.
