Yes, well, this is what we and many other hosts fear. Especially now as Airbnb has again moved the goalpost closer to the guest. I expect the refund scams to come out of the woodwork now.
We have so far been successful by simply avoiding Airbnb involvement in any type of guest management task, aside from getting bookings and getting paid. We deal with it outside of Airbnb. Prevention before they book is key to that strategy.
