If you have encountered a malicious add-to-cart by the same IP but did not pay, this will only affect the entire site or advertising data, and will not affect the GMC review. If the merchant does not want these data, there are several ways for reference: 1. Block some regions or countries 2. Turn on robot filtering in GA 3. Check the traffic source channel of malicious add-to-cart to see if there is a problem in the customer acquisition part In addition, due to factors such as network technology and peer competition, spam traffic cannot be completely avoided and can only be relatively reduced.
