ADVOCACY THROUGH NEGATIVE INTERNET USER REVIEWS
Review bombing; Review bombed; Review-bomb
A review bomb is an Internet phenomenon in which a large number of people or a few people with multiple accounts post negative user reviews online in an attempt to harm the sales or popularity of a product, a service, or a business. While a large number of negative reviews may simply be the result of a large number of customers independently criticizing something for poor quality, a review bomb may also be driven by a desire to draw attention to perceived political or cultural issues, perhaps especially if the vendor seems unresponsive or inaccessible to direct feedback.
