> A bad actor mod of a popular subreddit can persist for years, visibly, without people managing either to oust the mod, or to take down the sub's influence. This happens because the regular users have no power. I remember seeing some article that said a small number of mods control most of the popular subreddits. Many of them put their own bias into the system by banning users, banning sources, deleting content base…
When the mods of major subs are also mods for over a hundred other subs, you have to doubt how much actual moderating they are actually doing in their holier-than-thou positions.
It's also why expressing certain views is effectively forbidden across most of the site. These moderators have far too much control over the conversation.
