Online shoppers use the illegally obtained shopping platform account to place an order to purchase goods, and then use the member's quick return and refund function to repackage authentic goods with inferior goods or empty packaging, and sell the goods obtained through fraud on the second-hand platform for profit. Recently, the People's Court of Wangcheng District, Changsha City, Hunan Province, tried a fraud case involving a particularly large amount of money. It sentenced the defendant to seven years' fixed-term imprisonment, which was combined with three years' fixed-term imprisonment for the previous crime. It decided to execute eight years and six months of fixed-term imprisonment, and imposed a fine. Yao, from Anhua, Hunan Province, is a "post-00s", who entered social work after graduating from high school. Because of unstable work and tight money, Yao began to think about ways to get money quickly with less capital. Yao's rich online shopping experience made him notice the after-sales service vulnerability of an e-commerce platform (hereinafter referred to as "W platform"). For VIP customers, the platform has a quick return and refund service. If the customer is not satisfied with the goods purchased in the self run store of the platform, he can apply for quick return. The platform will refund the money in a flash after the courier receives the goods successfully. At this time, the package has not been returned to the warehouse, and the platform has not checked the authenticity of the goods, so the money has been returned to the customer's payment account. Thinking that he had found a business opportunity to "pull wool", Mr. Yao immediately called together his colleagues to test the feasibility of "changing civet cats for princes". In October 2020, Mr. Yao selected an apartment hotel as the place of transfer, and obtained the VIP account of "W Platform" by illegal means. Yao provided the principal to arrange others to place orders to buy dozens of pairs of sneakers of a certain brand, and then applied for goods return (replacement). When the couriers come to collect the goods, they use the fake goods prepared in advance to exchange packages, or directly send them back to the empty shoe box to buy "beads" and "casks", and then sell the authentic goods through the second-hand trading platform to make money. Within 20 days, Yao and others have successively transferred 500 pairs of shoes of the brand, with a total value of more than 400,000 yuan. After tasting the benefits, the criminal behavior of the fraud gang became more and more rampant. They frequently changed their hotels and even wandered to other provinces to commit crimes. There are also more and more kinds of goods to be swapped. In addition to famous brand running shoes, there are Bluetooth headsets, smart sports watches, iPhones, and so on. After noting the hidden problems of several login IDs that Yao has used for many times, "W Platform" associates 108 other platform login IDs with information such as receiving address, mobile phone number, account login device, etc. After retrieving the historical purchase orders of these ID accounts, the platform found that 657 order commodities were displayed as being transferred. In the first half of 2022, when Yao was arrested, he was sentenced to three years' imprisonment and four years' probation by a court in Nanjing, Jiangsu Province, for defrauding another shopping platform. According to the judicial audit, Yao and his associates (handled separately) defrauded "W Platform" of refunds and property totaling 669314 yuan by means of inferior goods, return of empty boxes and exchange of goods. During the trial, Yao confessed his crime and voluntarily confessed to punishment. After the trial, the court held that Yao, alone or in concert with others, fabricated facts, concealed the truth, and defrauded others of their property for the purpose of illegal possession. The amount of fraud was especially huge, which constituted a crime of fraud. In combination with the circumstances of the defendant's voluntary surrender and voluntary confession, the court sentenced him to seven years' imprisonment and fined him
