Thanks for the "heads up." I'm not certain what their angle is, but good to know. As a reminder to us all to reiterate to guests and potential guests to conduct all business and communication through the platform. As an aside, if the guest pays in cash outside of the platform, I doubt that AirBnB would honour any requests for damages, etc.
In this specific situation, if the guest has made an inquiry, a simple response from you stating that all transactions must be through the platform. I might then temporarily block off one of the nights so that they cannot make a request to book.
Hope you are well. Again, thanks for the passing along the info.
