On e-commerce platforms, some merchants may take unethical or even illegal measures to artificially boost product reviews, although these actions are usually prohibited by the platform and may result in severe penalties. Here are some common methods: 1. **Fake orders and fake reviews**: Merchants may hire professional fake orders teams or recruit individuals to fake purchases of products to leave positive reviews for the products. 2. **Fake user reviews**: Use fake user accounts to write positive reviews. These accounts can be obtained through purchases, bulk registrations, etc. 3. **Manipulated product samples**: Give free product samples to target users in exchange for positive reviews. 4. **Fake review content**: Modify or fabricate existing review content, or post fake user experience and good reviews on websites/forums. 5. **Incentive mechanism**: Provide coupons, discounts or other incentives to induce customers to leave good reviews. 6. **Manipulate review ranking**: Try to put good reviews at the top so that customers see positive reviews first when viewing reviews. 7. **Clear/suppress negative reviews**: Try to contact the platform customer service to delete or reduce the display of negative reviews, or put pressure on users who post negative reviews through legal or illegal means. Although these methods may increase product reviews and sales in the short term, once discovered, merchants may face serious consequences, including being banned by the platform, losing business reputation and facing legal risks. Therefore, companies should focus on improving product quality and services to win customer praise in a legal and ethical manner.
