The way it is actually engineered is that it is impossible to view a review, before leaving your own (or waiting until the review shows up, after which you can not leave a retaliatory review). For the ridesharing, it depends. Maybe the driver has a route they know well, or has friendly connect. Maybe traffic for you was very bad and chaotic and there was no click. For ridesharing I played tit-for-tat for a while, until I realized that I don't want to play this game (if my rating drops below a point where less drivers will pick me up, I will switch to Taxi's). For AirBnB: I never leave bad or lukewarm reviews, only good reviews. Getting a host that is actually there for check-in, really acts a host, is getting increasingly rare, so my good reviews are too.
