Common situations

1. Online shopping fraud. Criminals set up fake shopping websites or Taobao stores. Once the victim places an order to purchase goods, they claim that the system has failed and needs to be reactivated. Subsequently, false activation URLs were sent through QQ to commit fraud.

2. Low-price shopping fraud. Criminals publish transfer information of second-hand cars, second-hand computers, items confiscated by customs, etc. through the Internet and mobile phone text messages. Once the victims contact them, they will defraud money by "paying deposits" and "transaction tax fees".

3. Criminals use offers, discounts, overseas purchasing, etc. as bait in WeChat Moments. After the buyer pays, they then demand the goods on the grounds that "the goods have been detained by customs and additional duties must be paid." Additional payments will be made, and contact will be lost once the purchase payment is obtained.
