Hello from Amazon.
A review of your account indicates you may have violated our policies by not setting the “is_adult_product” flag properly on detail pages you created for adult products.
Our policies require all sellers comply with the criteria in accordance with our Adult Products Policies & Guidelines.
We want to call your attention to this policy because violations may result in the removal of your Amazon.com selling privileges. To learn more about this policy, search "Adult Products Policies & Guidelines" in Seller Central Help.
Please review your listings and make any changes necessary to comply with our policies. You can modify your listings on the Manage Inventory page in the Inventory section of your Seller Central account (https://sellercentral.amazon.com/myi/search/OpenListingsSummary).
