I could be wrong about this but I think they only post guest reviews of the property once the host has also reviewed the guest. So if the guest leaves a review the host doesn't like then they simply won't post a review for the guest. The only times I have not received a guest review from a host on AirBnB is when I have left a 4 star review (instead of 5.) The net result of this is that more properties have more 5 star reviews and so do more guests.
