In some online novels, the author will let the villain or conspirator use the diffusion mechanism of real social media to create and spread false information in order to attack competitors or undermine public trust. The general plot setting may include the following steps: 1. Create fake accounts and water army: The characters will register a large number of fake social media accounts, which appear to be from ordinary users but are actually controlled by the mastermind behind the scenes. These fake accounts will continue to publish and encourage some seemingly reasonable but actually well-designed harmful information. 2. Create seemingly authoritative news: In order to make false news more credible, the characters in the novel may forge news reports, create false evidence or tamper with existing information to make these news look like they come from regular channels or well-known media. Sometimes even some seemingly objective and neutral "experts" are invited to endorse. 3. Utilize the diffusion mechanism of social platforms: By adopting a "one-sided" forwarding, likes and comments method, false information quickly occupies the hot topic list. Algorithmic recommendation and hot spot tracking allow the originally scattered information to be quickly amplified, making more and more ordinary users believe it to be true. 4. Stimulate user resonance and panic: These false news often target sensitive areas of public concern, such as food safety, product quality, environmental pollution or health risks, and are likely to cause panic or anger among netizens. As social emotions ferment, the brand or image of competitors will be affected and trust will be in crisis, which will in turn affect their economic interests or market image. 5. Use public opinion pressure to attack opponents: After a period of information diffusion, false and harmful news will not only make the public suspicious of competitors, but may also cause regulatory authorities to intervene in investigations, thus bringing a double blow to competitors. On the one hand, there is a loss of market trust, and on the other hand, it may be accompanied by legal or public opinion difficulties. This method of using social networks to spread false news and create public opinion storms not only reflects the author's understanding of the information dissemination mechanism in reality, but also shows how villains in the fictional world use modern technology and media channels to achieve unfair competition. In novels, such plots not only increase the drama of the story, but also prompt readers to think about the risks and challenges of distinguishing between truth and falsehood in the information age.
