Airbnb hosts face costly revenge tactics from vengeful guests.

An Airbnb host in South Korea was charged $640 in utilities after guests intentionally left the gas on and drove up the water usage. The host claims this was retaliation because he would not accommodate a last-minute cancellation. The couple used 120 metric tons of water and high gas usage, which added nearly $130 and over $480 to his bill, respectively. The host allegedly asked for Airbnb’s help with the high utility bill, but the company said it wouldn’t be able to help with compensation in this case.
