It could just be that they joined and have never used the service until now. Whenever I get a reservation request I always ask the person to tell me a little about themselves and their reason for visiting so that i may help them determine if my space will best meet their needs. Many refuse, and then know in my gut that I should refuse their request.
Also when people ask questions that let me know they have not read the listing, I ask them to please read the listing to be sure it meets their needs. Many get angry at me asking them to read the listing and I figure this is just a problem avoided when someone gets pissed because you ask them to read the listing.
There is also the possibility that hosts don't rate them because they are so horrible and they do not want to seem like a complaining host. I don't rate many people who have been horrible because I don't want to seem a complainer. We have most people who are simply nice people but there are also horrible people, some, making it all the way to being a few steps away from being the leader of the free world, so obviously some of these people will find their way through AirBnB, as large as it has become. I had guests on Christmas day that wanted me to tip toe through my house because their teenage son, who was sleeping on the pull out queen sofa bed in the loft, needed absolute quiet because he needed to go to sleep at 8pm because he had a golf tournament early in the morning. Well, I live in a very quiet neighborhood, and I'm fairly quiet myself, talking in normal speaking tones within my home, but there was no way I was going to tip toe through my home whispering on Christmas Day. I offered to find her another AirBnB and waive the rest of the reservation. Some people just are not considerate. They could have given their son their private bedroom and slept in the loft bed themselves were they so concerned about him having 'absolute quiet'. Follow your instincts on this one.
