After clicking on the charity donation icon, they were redirected to a scam platform, where they met "netizens" and were induced to register a gambling website account. They scanned the QR code of a short video and were directed to pornographic websites... Recently, the Ministry of Public Security has released multiple typical cases of cracking down on advertising and promotion oriented online black and grey industry crimes. The online black and grey industry has now formed a clear division of labor in the industrial chain, among which advertising and promotion crimes are in the upstream. They not only directly infringe on citizens' personal information, but also help downstream illegal activities such as telecommunications fraud, online gambling, and illegal business attract customers, providing continuous "blood transfusion and food supply" to the criminal chain, posing a threat to public safety. In April this year, the public security organ launched a special crackdown. As of August, more than 170 related cases had been solved, and more than 460 suspect had been arrested, effectively curbing the high incidence of online black ash production crimes. With the strengthening of efforts to crack down on and prevent propaganda in accordance with the law in recent years, netizens have developed a certain ability to identify common scams such as "high return investment" and "brushing orders to receive rewards". So, on the one hand, advertising and promotion oriented network black and grey criminals enhance the concealment of their fraudulent methods, using seemingly formal shells to cover up the essence of their crimes. For example, they develop so-called recruitment software to deceive job seekers' personal information, and then distribute it downstream based on user characteristics to commit different types of crimes such as fraud, gambling, pornography, etc. On the other hand, improving the professionalism of technological means can directly damage computer information systems, such as tampering with enterprise and public institution websites, implanting web monitoring codes to obtain visitor information, etc., making it difficult for ordinary netizens to detect. They also use new platforms such as short videos and live broadcasts to package themselves as anchors and redirect viewers to gambling websites or group chats. Scams are constantly evolving, making it difficult to prevent. In the complex ecosystem of online black and gray production, traffic acquisition is a prerequisite for the development and expansion of criminal activities. Therefore, cracking down on online black and grey industries and addressing advertising and promotional crimes is a key link in preventing them from happening at the source. Relevant departments need to grasp the new methods and behavioral characteristics of advertising and promotion oriented online black and gray production crimes, strengthen technical screening and investigation warning, and enhance the effectiveness of the overall crackdown. For example, criminals may use a single mobile phone number to register and attract traffic on multiple platforms. Therefore, it is necessary to improve the database and warning system to ensure that a platform can promptly block and handle risks across the entire network, effectively enhancing targeted crackdown capabilities. Internet enterprises should conscientiously and strictly implement the main responsibility of network security management, upgrade their supervision ability, take management measures such as warnings, prohibitions, and blocking of high-risk accounts in accordance with laws and regulations, and squeeze the living space of advertising crime. At the same time, we will work closely with relevant departments to strengthen the investigation of criminal clues and potential risks, and jointly maintain a clear and orderly online environment. The low cost of crime and easy replication of patterns have led many people with weak legal awareness and insufficient social experience astray. In this regard, we should improve the accuracy of legal publicity and education, continuously strengthen the interpretation of the law based on cases, and focus on enhancing the legal awareness and prevention consciousness of key groups, so as to avoid becoming victims of online black and grey industry crimes and not being accomplices. Everyone is a participant and guardian of network security. We should enhance our awareness of security protection, not click on emails and links of unknown origin, not visit irregular and high-risk websites, not easily disclose personal information, be vigilant and consciously resist black and grey industry activities. Once we discover clues of illegal or criminal activities or personal rights violations, we should actively complain and report to relevant departments. (New Society)
