@Matthew1027 Certainly all users, both guests and hosts need to do some due diligence when booking or accepting.
Of course, either a guest who is new to the platform, or a host who is, won't have any reviews yet- we all have to start somewhere. I'm grateful to the guests (especially my first, who had zero reviews to go on) for taking the chance on me, and also very appreciative of the lovely reviews they wrote to get me going.
I always suggest to guests that if they have any wariness about a place, to message the host before booking. You can get a pretty good feel for someone by the way they communicate, and also if they respond quickly. Just because a place is instant-bookable, doesn't mean a guest can't send an Inquiry to the host first, before committing to a booking.
