We believe that this kind of behavior is extremely irresponsible, and we do not want this type of business; anyone who engages in or allows such behavior is not part of our platform. ” < / P > < p > affected by the business model, airbnb can not always prevent the party behavior of users. Some guests can sometimes go to remote houses to check in and gather many others, ignoring the rules. < / P > < p > there have been a number of incidents in which airbnb guests violated the room rules and held parties, at least one of which led to significant property losses. < p > < p > just yesterday, airbnb just announced that it had submitted an IPO (initial public offering) prospectus to the US Securities and Exchange Commission (SEC), but the size and price range of the offering have not been determined. < / P > < p > in a round of private financing in 2017, airbnb was once valued at $31 billion.
