Guests complain their reviews not showing

I dont' know why these guests' reviews are not showing...but...I think it would be a good idea if Airbnb learned to train their "algorithm" to remove reviews coupled with ratings that were very atypically low. For instance, a host has 100 reviews and an average 4.7 star rating. Then they get an across the board 1 star review/rating. It's pretty obvious that this is likely to be the result of a retaliatory guest, seeking revenge on the host. Hosts dont' suddenly have their listing change from a 5 star to a 1 star listing.

So I would be quite happy if Airbnb had discovered a way to remove these strikingly and very unrealistically low ratings.
