I'm having trouble with a listing in an area occupied by a competitor, and I've had several issues because of it. Recently, a guest booked using an account in another country. On the day of arrival, he called from numbers in my country. Unfortunately, (stupid me) I helped this guest resolve the issue over the phone, not through the Airbnb app. I answered calls at night, answered stupid questions, and ended up finding a dirty (litter-filled) apartment and a guest review. I contacted Airbnb, but aside from text messages and recorded phone calls, I didn't have enough evidence of the competitor's involvement. I found both phone numbers online, but for Airbnb, they're no proof of malicious activity. Have you had similar experiences? I feel like, as a host, I'm the problem for Airbnb. In critical situations, I have no way to defend myself and I'm always on the losing end.
