Air BNB decided to penalize the host by pause the listing. It is not fair for the host if the Traveller decided not to give any feedback or rating for whatever reason. Disappointed is Airbnb agreed the Traveller feedback rather take a feedback from the host.another thing. Some of the host also decided not to give any bad feedback or not to recommend the Traveller to any host for some reason too. But Airbnb only look at the one side only.
@Ann696 I highly doubt that Airbnb would pause a listing because some guest didn't leave a review. If many guests don't leave one you might not be able to become a Superhost, but there might be something else if Airbnb desides to "pause" a listing. Your title is not the same as the problem you are explaining though. If you have many low reviews you might get de-listed but that is not the same with certain guest not leaving a review.
