Airbnb doesn't let you leave a review if your stay was cancelled - which it will be if you experience real problems. Taobao, the largest marketplace in the world that can sell $38 billion worth of stuff per day, has the same problem. That's why it's such a mediocre experience for certain niches, e.g. books. First, you cannot leave a review if you return or even engage in after-sales dispute. Second, since this is a marketplace, you usually do not review the item itself, you cannot leave a bad mark if you don't like your new laptop, because the shop is just a seller. So 99.9999% reviews on Taobao are along the lines of "shipped fast, received in 2 days, not bad, a bit of plastic stench and the box was broken, 5 stars".
