Very intelligent question to pose and one all hosts should contemplate.
Unfortunately, the anwser is
"Airbnb can't do anything special for you. You are on your own."
If you are renting in a foreign country (or even a different city), you need to know the laws and standards of that area.
You probably need a presence or an agent to act on your behalf.
The police may or may not help you.
That said, Airbnb have called late stayers for me and argued that they should leave.
They also can charge their card, if still current.
They can deny these grests future Airbnb service.
But that is about all Airbnb can do
Right now, we are lucky using Airbnb. We are in the Sweet Spot, where not that many scammers have figured out how to abuse us yet.
