I'm writing here today to ask other hosts what they do about scammers. About once a year someone will book and then look very hard and long for a little piece of dirt or a spider or something and take a photo making it look way horrible then it is and send it to airbnb and demand their money back. Does anyone else ever experience this? Most of my guests are terrific but gee whiz sometimes you just can't please someone. They demand money back for the stupidest of things. What are some of your experiences?
