@Gail-And-Bill0 You don't jeopardize your Superhost status by leaving an honest review. You just have to be careful how you word it- you can't blantantly accuse guests of prostitution-type activities- try to write something that warns other hosts in a way that we can read between the lines. Also flag this guest's account.
But I have to ask why you were allowing unregistered guests to enter your property in the first place? As soon as I saw Ubers arriving, dropping men off entering the house, I'd have gone over, confronted the guests, reported it to Airbnb and booted them out.
