Airbnb is taking more steps to crack down on parties and nuisance guests in the wake of a Halloween shooting at an Airbnb rental in a San Francisco suburb where five people were killed. At the same time, the vacation rental service has scrubbed thousands of Boston listings from its platform following the launch of strict new city regulations on home rentals.

The company said Thursday it’s banning “open invite” parties at all of its accommodations. Those are parties open to anyone and advertised on social media, for example.

Airbnb says boutique hotels and professional event venues will be exempt from the new rule.

The San Francisco-based company is also banning large parties at apartment buildings and condos.

“This policy does not impact parties that are authorized by hosts and convened respectfully by guests,” the company said in a news release. “Instead, our goal with this new policy is to address the small number of guests who act irresponsibly and those rare hosts whose homes become persistent neighborhood nuisances.”

Airbnb says it’s in the process of identifying listings globally that may be violating the party house ban, including accommodations in Los Angeles, Miami Beach, London and Montreal. The company says it’s asking hosts to update their listings to comply with the ’’open invite” ban.

Airbnb is also issuing new guest behavior rules. In early 2020, guests will get a warning for one instance of excessive noise, unauthorized guests, unauthorized parking, unauthorized smoking or excessive messiness reported by a host or a neighbor. Further violations will result in account suspension or removal.

Airbnb CEO Brian Chesky announced last month that changes would be coming after five people were killed at a Halloween party shooting in Orinda. The owner of the Airbnb rental didn’t authorize the party, which had more than 100 guests.

According to Wired.com, Airbnb has scrubbed between 1,000 and 3,000 listings from the roughly 6,000 listings it advertised in Boston until recently. The move is in response to strict new city rules that require the company to share data with the city, that require hosts register with the city, and require hosts to live in the same building as the unit or room being listed. The rules were enacted in response to concerns some landlords converted normal apartment units and buildings into de facto hotels.
