The following content is for illustrative and academic discussion purposes only and should not be used for actual illegal activities. Malicious attacks on others’ reputation online are essentially acts of defamation and unfair competition, which may violate the legal red line. Understanding these methods can help companies and individuals better prevent and deal with false information attacks. The following are some of the false methods that may be used by criminals for reference: 1. False reviews and evaluations: • Use multiple anonymous accounts to post fabricated negative reviews on e-commerce, social platforms or evaluation websites. • Post false information in batches to create a public opinion atmosphere and try to influence potential customers and public impressions. 2. Create and spread rumors: • Spread unconfirmed negative rumors on forums, blogs, social media and other platforms. • Use "water army" or robot programs to forward and comment on a large scale to enhance the credibility and spread of rumors. 3. Fabricate and tamper with factual information: • Create fake news reports, pictures or videos to confuse information with facts and mislead the public. • Impersonate third-party organizations or media to publish so-called "exclusive reports" to mislead readers into negative perceptions of competitors. 4. Impersonation and account manipulation: • Create fake corporate or personal accounts, impersonate competitors’ internal staff or partners to publish negative information. • Use false qualifications and background information to add “authority” to the false statements published. 5. Hacker attacks and data tampering (illegal behavior): • Illegally obtain internal information and distort and quote it out of context to publish content with devastating negative interpretations. • Tamper with or forge official documents and announcements with the intention of creating public distrust of competitors. 6. Manipulation of search engines and information blocking (search engine optimization abuse): • Use SEO (search engine optimization) technology to suppress the ranking of competitors’ real positive content through a large amount of negative web page information. • Construct a large number of related negative content links to “cover up” the real information with the help of network algorithms. It should be emphasized that the above methods are often illegal or unethical, and with the improvement of Internet supervision and technical means, the effect of being exploited may be limited or even traced back. For companies and individuals, when faced with false information on the Internet, taking legal and compliant legitimate means (such as clarifying according to law, using public relations strategies, seeking legal assistance, etc.) is usually a more effective way to deal with it. At the same time, it is also recommended to continue to pay attention to and improve the online public opinion monitoring system, and to promptly identify and deal with potential risks.
