@Yu37 The Superhost concept is meant to show guests which hosts can be most trusted to deliver a great hosting experience. (as well as allowing Airbnb to exert mind control over hosts). It is not supposed to be an indicator of how hard a host tries behind the scenes.
@Yu37 If a host can't keep their properties in a state that earns high enough reviews to retain Superhost status, I'd say they are trying to manage more properties than they are capable of.
I don't see why anyone should be rewarded for that.
