In online shopping reviews, consumers may deliberately damage the reputation of merchants in the following ways: 1. **False reviews**: Users may post false negative reviews, fabricate purchase experiences, or exaggerate product defects to mislead other potential consumers. 2. **Malicious negative reviews**: Some consumers may give extremely bad reviews for personal reasons (such as disputes with merchants), even if there is no problem with the product or service. 3. **Photo forgery**: Uploading processed or forged product photos to show that the product is damaged or does not meet the description to support their negative reviews. 4. **Add false information**: Add untrue content to the review, such as claiming that the item has serious safety hazards or illegal issues, to cause public panic. 5. **Posting duplicate reviews**: Repeatedly posting similar negative reviews to create the illusion that the product has a bad review. 6. **Using social media**: Spreading negative reviews of merchants through social media platforms to increase their influence and lead more consumers to distrust the merchant. 7. **Manipulating ratings**: If the platform allows, consumers may use multiple accounts to manipulate ratings and deliberately lower the merchant's overall rating. 8. **Attacks on individuals**: Comments that attack the business or its employees personally, rather than just the product or service itself, lowering the business’s reputation. These actions not only damage the business’s reputation, but also mislead consumers’ purchasing decisions, so it is particularly important to maintain the authenticity and fairness of the comments.
