This question is directed to the Amazon Support team.
Our app got rejected because it facilitate illegal activities.
Everything that our app provides is under Creative Commons License. For every item we list, there is a license attached to it provided from the content owner himself.
After we stated that into the review section. The reviewer did not care and just rejected our app.
We understand maybe they have a lot of work to do but still take the time to read the comments we left.
We contacted the Amazon support team explaning the situation and waited a week to finally get an answer that shows The Amazon app store does not really care which I never thought could happen.
The answer we got was
We reserve the right to determine the appropriateness of all apps and to accept or reject any app at our discretion. Due to the high volume of submissions, we cannot address specific areas of concern with our content guidelines. Please do not resubmit these apps or similar apps in the future.
Basically we can reject your app please do not bother us anymore.
I am writing this here hopefully some amazon representative sees this and help us with this issue.
The case id
Best of luck to fellow developers out there.
