Camper fraud.
Currently I host. Last week I missed a message. The camper showed up anyway?! I thought he was another camper that was scheduled on another site. When checking the request had expired. The camper said he paid. His fee was reversed and I was never paid for his stay. I provided water, electric and sewer hookup. He will now not respond to me and Hipcamp seems to leave it up to me to collect from him.
