This surprises me, but it is consistent from Facebook's viewpoint where the user is the product. You can fire a customer, but you can't fire your product.

So maybe it is to be expected that Facebook implemented moderation as a QA process. It would probably be against their interests to implement policies that would police their community in a way that makes sense, with warnings, temporary and permanent bans etc.
