As mentioned by another comment, both host and guest submit their review before seeing the other's review. And they rarely interact again. Having looked at many property listings, and stayed at places with marginal reviews, I'm quite sure bad hosts get bad reviews. And I am pretty sure the same is true of guests. Furthermore, guests and hosts submit a review a very high fraction of stays, and one cannot submit a review without actually hosting or actually spending substantial money as a guest, so AirBnN avoids most of the problems that Amazon reviews have.
