This is terrible. The infuriating thing is if Amazon actually does anything, the scammers still get off with no penalty other than having their seller and Createspace accounts suspended.
If you don't mind me asking, is there a POD block printed on the bottom of the last blank page? Typically it's a barcode and something like "Printed in USA, Lexington KY" and the date.
Also on the Twitter thread someone mentioned that the contents were copied from a PDF you sell on the site -- are they the same press-ready PDFs used for the book, or PDFs formatted for 8.5 x 11? I ask because we sell PDFs too for letter-sized paper, and I always assumed it would be difficult to pirate for a 6x9 how-to guide.
