As a reviewer, I feel the pressure to leave five star reviews even when I did not have a five star experience because it seems like even just leaving a four star might hurt the venue since nothing lower than 5 is acceptable. I try to fight this urge and manage it with Google reviews, but with AirBNB it is hard since you talk directly to the owner a lot of the time and feel a sense of obligation to leave overly positive feedback. So I don't think we have so much of a 1-star review problem, but more of a polarised review problem. Everything is either 1 star or 5 star with not much in-between.
