In 2017, Airbnb was accused by travel blogger Asher Fergusson of failing to close dangerous loopholes allowing for scams by hosts. In many countries including the United States, France, Canada and the United Kingdom, Airbnb doesn't require hosts to provide any form of identification. A host who has been "permanently banned" can set up a new account under a different name and email address. Addresses are not verified so "bad" hosts can list lodging at any address, even if they don't control the property.
Violations occurring over a 4½ year period—from October 1993 to July 1998—targeted American Airlines for using high-sulfur fuel in motor vehicles at 10 major airports around the country. Under the federal Clean Air Act high sulfur fuel cannot be used in motor vehicles. American Airlines promptly identified and corrected these violations of the Clean Air Act.
Some cities have restrictions on subletting for a short period of time. Airbnb has published a list of regulations and requirements for cities in the United States. In some cities, collection of a transient occupancy tax by Airbnb is required. In many cities, hosts must register with the government and obtain a permit or license. Landlords or community associations may have restrictions on short-term sublets.
