Airbnb allows owners to delete reviews by customers. All they have to do is re-post their property as if it were a new one, and then withdraw the old property. That way, they can keep the 5- or 4-star reviews, even one or two 3-star reviews to look "honest," and create false representations. It then becomes impossible to tell apart good owners from bad ones.
