One thing I don’t like about Airbnb as a host is that. They don’t run back ground check again after the initial one. What if the guess that pass first time back ground check is now a serial killer after 6month or a 1 year and still continue to book Airbnb as a hide out place. The life of the host and their family is in danger unknown to them. Airbnb should be doing background at least after a year host will feel more secure and safe.
