I think it has become impossible to run a social site without any central moderation today. You will attract a certain group of people, and they will act more and more horribly and brazenly (generally harassing third parties) until you just have to delete something. Then they will accuse you of censorship, and the rest of the community will side with them, not you. The harassment will turn on you. Eventually you will snap, and then you are in a world of trouble. It doesn't matter how much free speech cred you have built up over the years. It happened to the founders of Reddit, Twitter and even 4chan. Of course I am painting site admins as too innocent here. Ultimately they brought it on themselves by letting the community norms fall off a cliff. Back in 2000-2010 being the rough underbelly of the internet was fun, but that period is definitely over.
