I have proof that at least one airbnb owner (if not more) in my building has been allowing people coming in to the country to quarantine here, which I believe goes against the CDC’s guidelines (I assume that because I’ve seen other airbnb owners write a notice that people who are quarantining are not allowed to stay here). Hundreds of people live in this building and we all share two elevators. I think this is very concerning. Is there anything I can do to shut this down? Is there a specific email or website or phone number I should contact?
