I have had about three people stay with me in two years who were probably up to something very dangerous insofar as trying to register a complaint bad enough where I would have been suspended.
1) A Chinese couple, who demanded that the house be quiet after 7:30 (no lights, noise of any kind) since the mother went to bed early with the baby. The husband actually got belligerent one night, kicking and yelling to be quiet at 8PM (quiet hours in the house after 11PM)
2) A woman two Christmas's ago, the stereotypical "Karen" (I am sorry to use that term). Pulled furniture away from the walls looking for problems, and was trying to find fault with anything in the room so she could get a refund.
3) A man last August, overheard upstairs in the residence talking about how they would call AirBNB and lie to get a refund by accusing me of racism and other false problems with the listings.
In *every single case* I avoided a disastrous situation by calling AirBNB first. I told them exactly what happened and that I was expecting a retaliatory review if not an outright complaint. In two of the cases, AirBNB actually read me the review first, letting me know what the guests had said, so I could respond accordingly. The Chinese couple actually didn't say anything negative, but I still wrote them up in the review about the husband yelling and kicking the wall.
So, AirBNB treated me okay but I have heard so many stories like yours. I can only be a good host, be very careful about who I let stay in the home, and even for the worst of people just try to get them out the door at the end of the stay without any major problems. I've never had to kick anyone out and never had to call the police so I guess I have been lucky.
