In online shopping reviews, some consumers may intentionally damage the reputation of merchants for various purposes. Here are some common methods: 1. **Posting false negative reviews** - **Fabricating problems**: Fabricating problems in product quality, service attitude or delivery speed, which do not actually exist. - **Exaggerating facts**: Exaggerating small problems that actually exist to make them appear to seriously affect the user experience. 2. **Using multiple fake accounts** - **Brushing negative reviews**: By registering multiple accounts, a large number of negative reviews are posted in a concentrated period of time to create the illusion that the merchant's reputation is damaged. - **Lowering the score**: Using multiple accounts to give merchants low scores and quickly lower the overall score. 3. **Posting biased reviews** - **Emotional remarks**: Using strong emotional words such as "bad" and "rubbish" to influence other consumers' purchasing decisions. - **Personal attacks**: Personal attacks on merchants or employees, beyond the problems of the products and services themselves. 4. **False pictures and evidence** - **Uploading forged pictures**: Providing damaged photos or usage scenarios that do not match the actual products to mislead other consumers. - **Provide false evidence**: fabricate or tamper with order information, logistics records, etc. to support their own negative comments. 5. **Organize and coordinate negative activities** - **Collectively give negative reviews**: coordinate multiple consumers to post negative reviews simultaneously through WeChat groups, forums and other platforms to quickly expand the impact. - **Incite others to participate**: encourage people around to give negative reviews, forming a vicious cycle. 6. **Abuse of platform mechanisms** - **Frequent reporting**: report the positive reviews of merchants for no reason and multiple times, attempting to lower the merchant's rating through the platform mechanism. - **Exploit loopholes in comment rules**: post content that violates platform regulations, trigger the platform to automatically filter or delete, and indirectly affect the merchant's evaluation. 7. **Combining negative reviews with after-sales disputes** - **Exaggerate after-sales problems**: deliberately create contradictions in the after-sales process and convert them into negative reviews to increase negative impact. - **Delayed evaluation**: take advantage of the delay of after-sales service and choose to post negative reviews during critical time periods to affect sales. 8. **Use competitors for malicious competition** - **Malicious slander**: competitors use various means to post negative reviews in an attempt to seize market share. - **False comparison**: Make false comparisons with your own products in the review to devalue the merchant's products. **Prevention suggestions (optional)**: Merchants can take the following measures to protect their reputation when facing potential malicious reviews: - **Monitor reviews**: Regularly check and analyze the content of reviews to detect abnormalities in a timely manner. - **Respond to reviews**: Actively communicate with consumers in response to negative reviews to demonstrate the merchant's responsible attitude. - **Report violations**: Report obvious false reviews or malicious behavior to the platform in a timely manner. - **Improve service**: Reduce the occurrence of real negative reviews by improving product quality and customer service. By understanding and identifying these possible malicious means, merchants can more effectively maintain their good reputation and protect the real interests of consumers.
