Airbnb began testing an algorithm in the U.S. and Canada to identify and block users who rent apartments for parties. System analyzes a user's positive reviews, their history on the platform, and the duration of their bookings. It assesses the distance from the house to the rented accommodation, as well as whether the selected dates fall on weekends or weekdays. Technology is already working in Australia and has reduced the number of unwanted parties there by 35%.
