Although it is unethical and potentially illegal to attack a competitor’s online reputation, some people may resort to the following fake means: 1. **Fake reviews**: Posting negative reviews on major review sites or social media platforms to disparage the quality of a competitor’s products or services. 2. **Fictitious complaints**: Creating fake customer complaints to influence potential customers’ views of competitors. 3. **Fake news**: Spreading fake news or articles to discredit a competitor’s reputation. 4. **Manipulating search results**: Pushing negative information to the top of search engine results through SEO techniques to make negative content more visible to others. 5. **Creating fake accounts**: Registering multiple social media accounts with fake identities to post false information and reviews. 6. **Malicious reporting**: Maliciously reporting a competitor’s content to an online platform in an attempt to have its account or content banned or deleted. 7. **Spreading rumors**: Spreading false rumors on online forums, groups, or social media to raise public doubts about a competitor. 8. **Fake websites**: Creating fake websites that are similar to competitors and provide misleading information or fake products. These means may not only harm competitors, but also bring legal risks and reputational losses to the attackers. Therefore, healthy competition should be based on integrity and morality.
