If competitors want to create negative news to affect a brand’s public image, they can usually use the following methods: 1. **Social media manipulation**: Use social media platforms to post negative comments, false information or misleading content to quickly spread negative information and cause public doubts about the brand. 2. **Rumor-mongering and rumor-spreading**: Spread negative rumors about the brand through anonymous channels or social media to create panic or distrust. 3. **Influencer-driven**: Work with social media influencers or people with strong credibility to publish negative comments or revelations about the brand. 4. **News submission**: Provide negative stories about the brand to news media, especially those involving consumer complaints or misconduct, to attract media attention. 5. **Use consumer feedback**: Encourage or guide dissatisfied consumers to post negative comments online to create public pressure. 6. **Information disclosure**: Deliberately disclose the brand’s misconduct or internal scandals (such as employee scandals, financial problems, etc.) to damage the brand’s image. 7. **Public opinion manipulation platform**: Create or participate in a special website or forum to focus on discussing and attacking a brand with negative emotions as the core. 8. **Law and litigation**: Using legal means to file lawsuits or complaints against brands, thereby arousing public attention and doubts about the brand. 9. **Crisis event promotion**: Creating crisis events (such as protests, demonstrations, etc.) when the brand is carrying out activities, and affecting the brand image through negative scenes. Although these methods have risks at the legal and ethical level, they may still be used by competitors in some cases. In business competition, it is crucial to maintain transparency and good communication to establish a positive brand image and customer relationship.
