According to the overall arrangement of the "Clear and Honest" series of special actions in 2025, the Cyberspace Administration of China has decided to launch a two month "Clear and Honest - Optimizing the Business Network Environment - Rectifying the 'Black Mouth' of Enterprise Network" special action nationwide. The special action focuses on the chaos caused by the online "black mouth" that harms enterprises, and focuses on rectifying four prominent problems. One is the problem of maliciously smearing, defaming, and attacking enterprises, including defaming and attacking the quality and operating conditions of enterprise products, fabricating false information to smear the reputation of enterprises, and making malicious complaints against enterprises; Organize and manipulate the "internet water army" and "black public relations", jointly release negative information related to enterprises, and maliciously attack enterprises or entrepreneurs; Carry out false and untrue evaluations such as commercial testing, testing to support businesses, and a combination of commercial testing. The second issue is extortion and blackmail against enterprises, including demanding "deletion fees" and "public relations fees" from enterprises under the pretext of "deleting posts" and "withdrawing articles" after releasing negative information related to enterprises; Using their own discourse power and influence, under the guise of "public opinion supervision" and "news supervision", they threaten enterprises to provide "protection fees" and so on. The third issue is malicious marketing hype, including maliciously gathering negative information about enterprises and tarnishing the development prospects of enterprises or industries; Distorting and interpreting public information or news reports related to corporate equity structure, financial statements, product packaging, etc; Stir up old news and events of enterprises, and engage in malicious marketing by taking advantage of hot events related to enterprises. The fourth is the issue of leakage and infringement, including impersonating and imitating the names and portraits of entrepreneurs in public account names, avatars, and profiles, publishing information under the guise of entrepreneurs, and taking out of context the past statements of entrepreneurs; Spreading discriminatory remarks about regions and groups, stigmatizing or maliciously belittling entrepreneurs, etc. Continuously pushing user preference content through algorithms, exacerbating the "information cocoon"; To pursue traffic and popularity, weighted recommendations are made for vulgar and obscene information; The problem and risk of algorithmic recommendation mechanisms on website platforms have always been a concern, as they recommend highly homogeneous content and induce users to become addicted. The reporter learned from the Cyberspace Administration of China that since the launch of the "Clear and Clear Network Platform Algorithm Typical Problem Governance" special action, the Cyberspace Administration of China has urged and guided key platforms to optimize information recommendation algorithm functions and adjust information recommendation algorithm rules in response to the risks of algorithm recommendation heating vulgar information, exacerbating "information cocoons", and increasing viewpoint polarization strongly reflected by netizens. Key platforms actively responded, signed the "Algorithm for Good" Nanning Declaration, improved the review of algorithm recommendation content, opened specialized websites, channels or accounts to publicly disclose algorithm rules and principles, developed and launched innovative functions such as "Cocoon Room Evaluation" and "One click Cocoon Breaking", improved user interest preference management services, and enhanced the diversity of algorithm recommendation content.
