For quite a while now, we've pointed out that doing any serious content moderation on major internet sites is laughably difficult, if not impossible. Whether done in a purely automated format, or with real human oversight, everything ends up boiling down to just how much collateral damage are we all willing to accept when sites attempt to enforce moderation rules. Even when sites attempt to communicate the rules to the public in a somewhat transparent fashion, such as Facebook, it all inevitably goes to the kind of hell that includes nixing accounts for sharing what is purely art.

But when sites don't bother to tell their users what the rules are, even after exacting punishment for violation of those rules? Well, that's when you have a bunch of Twitch streamers wondering what the hell is going on.
