If you live in New York, you've probably seen the subway ads for AirBnb. They display hosts who have made serious money through the tech company—the king of the "sharing economy." AirBnb has recently won significant legal battle by proving its own legality. It was ruled that AirBnb hosts who live in the apartment or house they are renting out are within the boundaries of the law. Well, that’s us. We’re legal. And yet, if I’m honest with myself, AirBnb has basically ruined my life. And it can ruin yours, too.
