When a host declines or cancels a reservation they feel uncomfortable with or unsafe with. Due to instant book these guest have access to my phone number. How can we prevent or report harassing behavior if they abuse the information they have privialge to as there is no review that will take place. Can airBNb not just make a rule that canceled guests are not aloud to contact host unless through the message thread this should go for guest that have an open case for Host Garentee.
