This guest found cameras in his bedroom, pointed at the bed, which if they were on and recording, amounts to a felony crime in many if not most states. The guest would have liked to be spared this horrible situation, but it may help for the guest to understand that hosts also have really horrible situations with guests, which they would also like to be spared. The guest is considering suing Airbnb over this situation, but I don't think it's fair to expect Airbnb to be able to prevent every possible bad experience with a host, just like they can't prevent bad experiences with guests. WHich is why both guests and hosts need to do their due diligence.
