Just for information.

Based on my over 45 years experience as an accountant and over 24 years of teaching accounts, one of my free e-books (on the subject) from a particular site has been downloaded, cover changed and is being sold at $10 on Amazon by an unprofessional (or is it professional?) plagiarist who has left digital trails for me to lodge a complaint with Amazon.

Waiting for a response from the e-commerce giant.
