If the guest rejects or ignores your request Airbnb provides no support to you. My house rules are listed online with my listing in the rental contract with the fees for breaking the rules listed also, like for smoking and leaving trash in the house. My guests brought in extra people, broke three other house rules, and refused to pay the fees and even though I used the reslution center and supplied pictures and text messages where the guest admitted smoking, they paid me nothing. House rules mean nothing to Airbnb. They denied my request and Airbnb closed the case, leaving me no recourse except to stop using them for renting my house.
