AirBnB doesn't seem to take reasonable steps to protect either side. I remember I rented out a place and I had no hot water for a week and the place was filthy. AirBnB's response was along the lines of, sorry, good luck finding a better host next time!

Maybe AirBnB needs to create educational video instructions on how to act as both a Host and a Guest. Hosts and Guests seem to be uninformed on how to behave and these common sense practices don't really seem to be common, for whatever reason.
