In the digital age, online platforms have become important places for commodity transactions, and the rapid development of e-commerce has also brought new legal challenges. In August 2024, an e-commerce company was hit by a wave of malicious negative reviews on the internet, which not only affected the company's reputation but also crossed the legal red line. This article will use this case to interpret the law, explore the legal consequences of malicious negative reviews on the internet, and how to maintain fairness and justice in online transactions. Suddenly receiving a large number of concentrated negative reviews, customers reported problems with product quality. After verifying with the production factory, the company found that these negative reviews did not match the facts, indicating that someone deliberately smeared them. After investigation by the public security organs, the truth has surfaced: another e-commerce company in Liaocheng, Shandong, organized employees such as Zhu and Yao to systematically purchase the company's products in order to crack down on competitors, and posted malicious negative reviews on its website. This behavior seriously violates relevant laws and regulations. Zhu, Yao, and others confessed to the illegal facts without hesitation. According to the law, the public security organs in Jinan City have imposed administrative penalties on the two individuals in accordance with the law. This case has important warning significance. Firstly, it tells us that the internet is not a lawless place. On the Internet, any individual or organization shall abide by laws and regulations and shall not damage the legitimate rights and interests of others by means of malicious grading. For e-commerce enterprises, in the face of malicious negative reviews on the internet, they should actively take measures to safeguard their own rights and interests. On the one hand, enterprises should communicate with consumers in a timely manner, understand the real situation behind negative reviews, and provide timely after-sales services to safeguard consumer rights and interests; On the other hand, enterprises should collect evidence, report to platforms or public security organs, and firmly resist malicious negative reviews. In summary, the online malicious negative review incident that the e-commerce company encountered this time is not only a legal ruling, but also a profound education on online integrity management. The majesty of the law cannot be challenged, and the light of justice will surely illuminate every corner. The internet police remind us to urge all consumers to raise legal awareness, make rational evaluations, and not participate in or disseminate unverified information. The clarity of cyberspace requires the joint efforts of each and every one of us. Let us work together to maintain a fair, honest, and orderly online trading environment, and contribute to the healthy development of e-commerce. (New Society)
