PANews reported on January 7th that multiple regions, including Shanghai, Yunnan, Gansu, and Hainan, have issued warnings about "free trial card" scams involving virtual currency. Some criminals are using the guise of "freebies" from well-known supermarkets to drive traffic to telecommunications and online fraud crimes. Police explained that the suspects responsible for attracting traffic use overseas communication software to connect with fraud rings. After distributing each "free trial card," the ring takes a photo of it individually, recording key information such as the community address, house number, and fake promotional materials hanging on the doorknob, and uploads this information to their superiors. They then periodically settle payments with virtual currency, making the scam highly covert. Police remind the public not to participate in such "ground promotion jobs" for small gains, lest they become accomplices to fraudsters and bear corresponding legal responsibility.
