Aaron Parecki
has POSSEd at least one review (posted as a note), to Amazon since 2015-06-23:
 * Original review: http://aaronparecki.com/notes/2015/06/23/1/echo
 * POSSE copy: http://www.amazon.com/gp/customer-reviews/R3SBOFS3P8WJC4/ref=cm_cr_pr_rvw_ttl?ie=UTF8&ASIN=B00X4WHP5E
 * Later, after applying to the Amazon.de affiliate program, the application was denied because the wbesite "uses unauthorized, trademarked words, images or reviews from Amazon ... You can find an example of the above violation here: [ https://aaronparecki.com/reviews ]."

Amazon Author Pages
Amazon provides "Author Pages" for book authors, which you can set up through their "Author Central" tool.

If you are an author of a book listed on Amazon, you can create your own author page.


 * https://authorcentral.amazon.com/

You will need to verify your email address, then you'll be able to "claim" books on Amazon that are yours. Once you've logged in, you're given a dashboard where you can customize your author page, including adding a photo, choosing a custom URL, adding a bio, and even import a blog RSS feed to show on the page.

Author Central cannot be used to update any product information about your books.
