I have the same question. all the responses on here sound like everyone thinks you should go on faith. we received a request at 2am, the name is one letter (J), nine years on airbnb, no reviews. our listing is a house that is very large on 5 acres but booking request is for 1 man & 1 dog. I think its ok not to go out on a limb. first timers or new to airbnb is ok, but 9 years and zero reviews??? I think we need more guidence on how to decline respectfully and gracefully if need be.
