There are many strategies for spreading false information on online platforms to influence public opinion. Here are some common methods: 1. **Fake accounts**: Create fake social media accounts that imitate real users or celebrities to increase the credibility and reach of information. 2. **Bot programs**: Use automated programs (i.e. "bots") to quickly spread false information on social media to create the illusion of widespread support. 3. **Hot topic manipulation**: Take advantage of current hot events or topics to incite public sentiment and the direction of topic discussion through false information. 4. **Selective information dissemination**: Selectively publish certain information or fragments, ignoring relevant context and facts to mislead the public's views on issues. 5. **Fake news websites**: Create professional-looking fake news websites that publish false reports and use search engine optimization (SEO) to increase their visibility. 6. **Image and video forgery**: Use image processing software or video editing tools to create fake pictures or videos to enhance the credibility of false information. 7. **Emotional manipulation**: Use people's emotional reactions (such as fear, anger or joy) to attract attention and share, thereby accelerating the spread of false information. 8. **Social network bubbles**: By building internal social networks, people with the same views are gathered together to form information echo chambers, which reinforce specific false beliefs. 9. **Using algorithms**: Using the algorithms of social media platforms to increase the exposure of false information through a large number of interactions (likes, comments, and shares). 10. **Confusing the truth**: By publishing partially true information and mixing false content with the audience, the purpose of confusing and misleading is achieved. 11. **Spreading conspiracy theories**: Spreading information about conspiracy theories, relying on people's curiosity and skepticism to increase the appeal of false information. These strategies are highly concealed and influential in the modern information dissemination environment, so improving the public's media literacy and information discrimination ability is an important measure to deal with false information.
