Transnational gangs set up thousands of "five-star reviews" stores on Amazon and eBay, selling counterfeit electronic products, with annual revenue exceeding US$500 million. Consumers were threatened to "sue the bad reviewers" after complaining.
Core team innovation:
Raj Patel, head of CFIT's e-commerce fraud team, designed a "fake review AI detection model" to capture more than 100 million reviews and identify the water army network through semantic analysis and IP clustering:
It was found that the same batch of Vietnamese IP addresses were used to brush reviews for 200 stores.
Logistics data comparison shows that "domestic shipments from the United States" are actually direct mail from Shenzhen warehouses.
Global partner network:
China's Ministry of Public Security: Seized three counterfeit factories in Shenzhen and Dongguan.
Amazon: Cooperated to close stores and compensate consumers.
PayPal: Frozen US$120 million in funds involved in the case.
Legal expansion:
According to the "E-commerce Platform Accountability Act of 2023", CFIT sued platform algorithm engineers for assisting in counterfeiting for the first time, establishing a precedent of "technical accomplice".
