@Karen499, last month I had a series of three requests in a row, which were not satisfactory and I had to decline them (two of them were actually a boyfriend and then a girlfriend using two different accounts).
My acceptance rate dropped down to 91%, and nearing the 88% threshold, I became a bit concerned, so I contacted Airbnb. They told me the acceptance rate isn't really all that important and as long as I am keeping my response rate at 100%, then not to worry about the acceptance rate.
I questioned why have the 88% on the basic requirements then, and they said it is just a suggestion. They reiterated that they want the response rate at 100% and as long as it is, then not to worry about the acceptance rate.
