There  wasn’t any language to specifically say that linking to Amazon in an unnatural way is against its policy. We see it as a larger issue of trying to manipulate its system, and the new policy does make several mentions of intentional manipulation. But if a seller receives a policy violation or account suspension, we don’t think an argument like “I was trying to manipulate my products’ search position, not its sales rank” would go very far to bring your account back into good standing.
