• Visit Yelp’s Web site (www.yelp.com) and search for reviews for a service from a local business with which you are familiar. Do you notice any reviews that are overly negative or that seem to border on defamation based on your experience with this business? Are there any reviews that are so positive that they sound like they were written by or paid for by the owner? Imagine that you are the Web site owner and want to automatically filter out such reviews. How might you do this in an ethical manner?
