It used to be the case Reddit itself would run spambots, and if you reported them you'd be banned. Also they have a habit of, if a subreddit isn't moderated how they like, finding excuses to ban the moderators and then either ban the subreddit for being unmoderated or replace the moderators. There were also times they just replaced a moderator list because they didn't like how the subreddit was moderated if there was a financial or reputation incentive to do so. Are these things not still the case?
