AI-based online brand protection company Wigofair said on Tuesday it has strengthened its database of counterfeit sellers as part of its response to those exploiting Coupang’s Item Winner structure. It said unauthorized sellers can reuse official product images, descriptions and accumulated reviews by undercutting prices. Wigofair said it analyzes seller data to automatically group related accounts and respond in bulk once counterfeit activity is confirmed, working with brands and using reporting histories to track organized sellers across platforms.
