You need to read up Amazon policy on what you are allowed to do on a listing. Sellers can do a lot of things, it doesn’t mean they are allowed to or are immune to suspension:
When you create product detail pages on Amazon, you agree to the following rules and restrictions:
Using page-creation tools for any purpose other than creating product detail pages is prohibited.
The use of false product identification information, including UPC codes, in product detail pages is prohibited.
The "Add a Product" feature is to be used only to create pages for products that do not already exist within Amazon's catalog. Creating a product detail page for a product already in the Amazon.com catalog is prohibited.
Using the "Add a Product" tool to cross-merchandise or cross-promote a product is prohibited.
For Books, Music, Videos, and DVDs (BMVD) a single detail page may not be used to advertise more than one product. BMVD-only product bundles must be defined by the publisher or manufacturer and have a single ISBN, UPC, or EAN that is different from the product identifier for any unique item in the bundle.
Detail pages may not feature or contain Restricted Products.
The inclusion of any of the following information in detail page titles, descriptions, bullet points, or images is prohibited:
Pornographic, obscene or offensive content.
Phone numbers, physical mail addresses, e-mail addresses, or website URLs.
Availability, price, condition, alternative ordering information (such as links to other websites for placing orders), or alternative shipping offers (such as free shipping).
Spoilers regarding Books, Music, Video or DVD (BMVD) listings (information that reveals plot elements crucial to the suspense, mystery or surprise ending of a story).
Reviews, quotes or testimonials.
Solicitations for positive customer reviews.
Advertisements, promotional material, or watermarks on images, photos or videos.
Time-sensitive information (i.e., dates of promotional tours, seminars, lectures, etc.).
When creating a listing or when matching a listing to an existing listing, sellers must follow Amazon listing standards for any product sold on Amazon.com.
All products should be appropriately and accurately classified to the most specific location available. Incorrectly classifying products is prohibited.
Product titles, product descriptions, and bullets must be clearly written and should assist the customer in understanding the product. These attributes should comply with the category-specific style guide recommendations.
All product images must meet Amazon.com general image standards as well as any applicable category-specific image guidelines.
*Using bad data (HTML, special characters */? etc.) in titles, descriptions, bullets and for any other attribute is prohibited.*
All products listed on Amazon.com must meet North America product safety standards. Learn more about Choking Hazard Warning Requirements (CPSIA).
When creating a product detail page, provide only information that pertains to the features of the product in general, not the condition of your particular item. Product detail pages may be used by any other seller to list the same product. When listing an item for sale, sellers must use the offer listing pipeline. Within the offer listing pipeline, sellers are provided an opportunity to note their item's condition, quantity, price, and other seller-specific details that are relevant to a specific listing.
*Do not include HTML, DHTML, Java, scripts or other types of executables in your detail pages.*
