That being said I think from my personal experience that there is a bigger problem with the service. I got a very bad experience from a relatively new all-5-star host. The host lied to us and AirBnB, tried to get more than $1000 for various claims and so on. At the end AirBnB did a very poor job at mediating the claim. Then I wrote a review. I tried to be as objective as possible. AirBnB simply deleted the review. They didn't ask us to correct anything or anything. They straight out deleted it.
I believe that by doing so AirBnB is misleading both guests and their investors. This creates an impression that the service is better than it actually is. That is likely inflating their stock price. I personally believe that there should be a class action lawsuit or Hindenburg research paper about this for them to do anything about this.
