Airbnb has announced that it will detect and block higher risk bookings during holiday weekends to try to prevent house parties. Red flags include short-term stays, distance from the customer to the listing, and last-minute bookings.

Airbnb banned parties in 2020, and has seen 55% fewer reports of such events since.

In addition to using its own technology, Airbnb asked neighbors to report party concerns to Airbnb’s “24/7 Neighborhood Support” line, which is available on its website.
