Air bnb should block and not allow a guest who breaks the house rules and also brings additional guests more than the house accommodates without the owners knowledge until days after checking in then the guest threatens to leave a bad review. Air bnb should not allow that guest to leave a bad review because they are only doing it for revenge they are the ones who broke the rules so why should they be able to write a review if you as s guest breaks the rules that you agreed to then your rights to review the stay should be taken away.
