In the reputation economy, the ratings go both ways.
On a recent episode of the television series “South Park,” the character Cartman and other townspeople who are enthralled with Yelp, the app that lets customers rate and review restaurants, remind maître d’s and waiters that they will be posting reviews of their meals. These “Yelpers” threaten to give the eateries only one star out of five if they don’t please them and do exactly as they say. The restaurants feel that they have no choice but to comply with the Yelpers, who take advantage of their power by asking for free dishes and making suggestions on improving the lighting. The restaurant employees tolerate all this with increasing frustration and anger — at one point Yelp reviewers are even compared to the Islamic State group — before both parties finally arrive at a truce. Yet unknown to the Yelpers, the restaurants decide to get their revenge by contaminating the Yelpers’ plates with every bodily fluid imaginable.
