Today a shirt of mine has been rejected and I was able to minimize the location of the bad guy among the input fields from four to two. I wanted to learn which words I used and violated the content policy.
To make learning easier I recommend that Amazon will add a detail page which shows the rejected design and the text from the brand, title and bullet points. This will help designers to find the violations and learn from it.
I have no doubt that I made a mistake and I want to avoid it in the future. Knowing these words would make learning easier for myself.
Thanks and keep designing.
