As much as us HNers like to talk about technology, moderation of content is the key to any social media platform being successful. Moderation goes away or drastically changes and the users leave when the site fills with garbage.

Occasionally mods will duck out for a day, on purpose, to let members go nuts with content. That is what would happen without moderators and after a while, all those un-moderated subreddits would become cess pools of bot content and spam with members leaving and traffic will take a giant nose dive.
