2. Because the Douyin platform stipulates that merchants cannot induce consumers to give good reviews by means of cashback or gifts for good reviews, which will affect consumers' purchasing decisions and the reputation of merchants, thus violating the platform's code of conduct.

3. For Douyin stores, if they want to improve their reputation and user experience, they can take other ways to carry out promotional activities, such as discounts, gifts, etc., to attract consumers' attention and purchases.

Cashback for good reviews in Douyin stores is illegal. The Douyin platform prohibits cashback for good reviews, and this behavior is illegal on the platform. Cashback for good reviews means that consumers give sellers good reviews after completing online shopping transactions, and send screenshots of the good reviews to the sellers, and the sellers then return a small amount of cash or shopping coupons to the consumers.

The cashback for positive reviews in Douyin stores is not illegal in itself, but if merchants use fake transactions, fake orders and other means to obtain good reviews, it is a violation. In addition, the Douyin platform also stipulates that the cashback for positive reviews shall not exceed 10% of the product price, otherwise it will be regarded as a violation. If merchants violate the regulations, they may be punished by the Douyin platform with warnings, fines, or even account suspension.

Fabricating user reviews is a violation, and the platform prohibits merchants from cashing back for positive reviews in order to ensure fair competition on the platform.
