I am very sorry to hear that. It sounds like your privacy and your guest’s privacy, sense of security and general well being were put into jeopardy by over-reach of the government. If I were there, I would’ve asked to see a warrant and refused to answer any questions. Of course most people don’t think that way and will cooperate. They have their evidence and because an adult who was authorized to be there gave consent, that evidence is admissible.
For now, I wouldn’t do anything. If you get trouble from the mayor’s office, I would delete the listing and possibly your account and then start fresh. Don’t list the exact address, just the street. Don’t list the number of the unit or provide pictures of the building, from a window, of your front door or anything that could possibly identify your unit from outside. Don’t use your real picture or your real name on your account. I do all of these things myself and its not because Airbnb is illegal where I am. Its because its nobody’s business and once you start making money, everybody gets mad and nosy that they can see you’re making money and they aren’t. Now if you had legitimate complaints coming in from neighbors, that would be different. But don’t give anyone ammunition to stalk you with, look your information up online, talk to a landlord, talk to the mayor or anybody.
