Businesses no longer survive by word-of-mouth alone. Increasingly, business reviews are spread not person-to-person but instead online to the world at large. Websites and social media sites, such as Yelp and Facebook, provide a wealth of information to prospective customers. But they can also provide a platform for disgruntled customers to air their grievances. The law provides businesses with a potential recourse against a dishonest, negative review through a defamation lawsuit. A recent New Jersey appellate case sends a warning message to would-be online reviewers to ensure the accuracy of their reviews, while also cautioning businesses that any legal action can be lengthy and success is not guaranteed.
