These things pop up like whack-a-mole. I went ahead and reported them.
In general, customers seem to be pretty good at distinguishing garbage on Amazon from the real deal, and my actual listing has enough reviews that it clearly stannds out as the one they want.
Personally I often go to Amazon to find things, google the author and check on the HP on how to buy the book with the least amount of "tax" for the author.
Added benefit: you get formats outside of walled gardens!

Thanks for letting me know.
