I recently had two guests message me and ask to cancel a reservation the day before the booking, and one of them it was during his reservation.
It's clearly posted in the listing about the cancellation policies, and I believe Airbnb is responsible for bad reviews, for advising guests to request changes from the hosts and not abide by the policies in the listing which they previously agreed to.
This makes hosts look bad and not provide the best quality of service to future guests,
Airbnb should revise their recommendations to guests so they don't make hosts look bad for following policies.
Very upset about this situation and called customer service twice and they were unwilling to help.
