I just stopped leaving reviews. Airbnb pesters you so much to leave a review, and for what do they give you for it? Nothing. In fact, writing an honest review can be dangerous.
Contrast with a hotel, which -might- send you a short survey a few days later and then never bother you again. And if you do fill out the survey with a legit complaint, execs take notice and are motivated to give you discounts/free nights. Or at least an apology.
