In the digital age, online reviews are a powerful tool for consumers. However, a worrying trend known as 'review bombing' is on the rise. This is not about one unhappy customer leaving a single bad review. Instead, it involves a large group of people coordinating to post hundreds of negative reviews for a business, often as a form of protest. The goal is to damage the business’s online reputation, regardless of its actual service quality.

So, what triggers such an event? Frequently, the cause is a social media controversy. For instance, a video showing poor customer service at a Vietnamese restaurant can go viral, sparking public anger. This anger can then transform into a deliberate online campaign to 'punish' the establishment by flooding its Google Maps page with 1-star ratings. The motivation is not to provide honest feedback, but to use the review system as a weapon of public justice.

The consequences of review bombing can be severe. A sudden wave of negative reviews can destroy a small business’s reputation and financial stability overnight. The fairness of this practice is highly questionable, especially when many of the negative reviews are not from genuine customers who have actually visited the place. They are simply from people who are angry about the online controversy and want to participate in the protest.

As a young consumer, it is crucial to be critical of the information you see online. To spot potential review bombing, look for a sudden, massive increase in 1-star reviews over a very short period. Instead of just looking at the overall star rating, read the detailed comments. Being a responsible digital citizen means using reviews to make informed decisions for yourself, not to participate in an online mob that can unfairly ruin someone's livelihood.
