@Lisa722 I can think of at least 10 reasons why one would not want such a list to be available. Security and privacy are at the top.
If hosts belong to a private Facebook group in a particular location and agree to share data, that's one thing. To have public lists of Airbnbs circulating is really something else entirely.
One time, someone I know in my neighborhood who used to offer an Airbnb space asked if she could walk though my space and take a look, because she was going through something personal, and wanted to rehouse her guests.
I declined to allow that. Guests she had booked may have been perfectly lovely, but also may not have been a fit for my space at all, so I couldn't guarantee accepting any of them. It could have been a nightmare for me and for her guests.
