Moving forward, a majority of reservations will require credentials like a government ID or confirmation of personal information when booking in any of the platform's top 35 countries and regions—which account for 90% of all bookings.Following a trial run in August, meanwhile, Airbnb is rolling out anti-party tech that roots out potentially high-risk reservations based on a user's history, reviews, duration of membership, length of planned trip, distance to listing, weekend vs. weekday booking, and more.The firm hopes to curb disruptive and dangerous events—like the Halloween 2019 shooting that left five people dead at a California rental property.Guests who are flagged by the system and unable to make entire home bookings can still reserve a private room (where the host is more likely to be on site) or a hotel room.For property owners looking to get into Airbnb rentals, the company today introduced Airbnb Setup, which will provide every new host with free, individual guidance from one of 1,500 Superhosts in more than 80 countries, and give newbies the option to welcome an "experienced guest" (with at least three stays and a good track record) for their first booking."
