Core Viewpoint - The article discusses the complexities and potential issues surrounding the authenticity of products in the cosmetics industry, using a scenario reminiscent of a "Werewolf" game to analyze the roles involved in a product's supply chain and their respective levels of suspicion [4][12]. Role Analysis - **Role 1: The Streamer** The streamer has no suspicion as they did not handle the product directly, which provides them with a solid alibi [4][6]. - **Role 2: The Official Flagship Store** The flagship store theoretically has some suspicion, but the likelihood is low since they are the manufacturers of the product. The cost of producing counterfeit goods would outweigh the benefits [4][6]. - **Role 3: The Warehouse** The warehouse has significant suspicion due to the potential for employees to substitute genuine products with counterfeit ones during the packing process. Such behavior is not uncommon in warehouse operations [6][7]. - **Role 4: The Courier** The courier has some suspicion, but it is limited. The likelihood of tampering is lower for non-high-value items like cosmetics compared to electronics or luxury goods [8][9]. - **Role 5: The Consumer** Consumers have some suspicion, but it is also limited. The brand's refusal to accept consumer-submitted tests is reasonable, as there is no way to verify the authenticity of the product brought in by the consumer [9][10]. - **Role 6: Other Consumers Returning Products** There is a clear suspicion regarding other consumers who may have swapped genuine products with counterfeit ones during the return process. This scenario highlights a systemic issue rather than individual wrongdoing [11][12].
