"AirBnB is already very strict with landlords: it needs to start being a lot stricter with its users too." It's not as strict with landlords as it should be. And while it is strict with users it actually favors landlords and by a landslide. Have you ever rented long term with AirBnB? Hosts can literally cancel the reservation for any reason( Airbnb says they punish for doing so but rarely if ever because the Host can provide any reason) If you happen to be in a city that doesn't have as many Airbnbs and you get a really good deal, you're screwed if the host decides to cancel. Costs for Airbnb's have also gone up significantly that it's often not even worth it to rent one if you happen to be less than a group of 4 people.
