@Melissa346 No, to me it's still absurd. You are complaining about getting bad guests and the fact that you can't tell they are bad because they have dishonest 5* reviews. Indicating that you would decline their bookings if you saw that they only had 13 great reviews out of 30 stays. But then you say your objective is to fill your units- and you get 75% bad guests.
Guests look at the reviews that are left for you, not the reviews you leave for other guests. And even if they do research the reviews you left for previous guests, if they are good, responsible people, they have nothing to fear re a bad review. The ones who would be afraid to book with you are the bad guests you don't want.
Again, please use the review process the way it was intended. To speak the truth.
