Being a seller at Amazon, our client understood that negative reviews could potentially damage the prestige, profitability and trustworthiness of their business. The main objective of our client was to contact and communicate with the customers who placed negative reviews for their product on the Amazon review page. But, as there is no way to contact customers as contact information is not displayed on the review pages, he wanted us to build an extension that leverages the deeply buried hidden relation inside Amazon page DOM and reveal the contact information and help identify the customer from the Amazon review page itself. He also wanted to minimize as much as possible the unauthorized use of this extension.
