Airbnb is implementing "anti-party technology" globally to prevent guests from hosting New Year's Eve parties in rental homes. Utilizing machine learning, the platform identifies potential party reservations based on various signals, particularly targeting entire home rentals. Since 2020, Airbnb has enforced restrictions and required guests to sign agreements against hosting parties. In 2022, they blocked nearly 74,000 party-related bookings, aiming to ensure safety and reliability for hosts.
