Consumers can ignore negative reviews of merchants' after-sales services, as long as the merchants do not violate relevant national laws and the product quality is up to standard. Merchants are not afraid of being criticized. If consumers complain and sue merchants for legal or illegal after-sales services, the merchants have to hire lawyers to resolve the issue, which is a lose-lose situation for both consumers and merchants. In serious cases, merchants may close their shops or go to jail. Right and wrong are judged by interests, and fame depends on bragging.
