This is probably a trick as old as KDP. Normally, they just try to get credit card numbers and then don't deliver the book. They are notorious for not replying to the contact emails. I wouldn't worry about it. And yes, my books are listed all over these sites and have been for ten years. The book only being available in pdf is a big sign they don't really have it.robert eggleton said:I sent the outfit a DMCA on its contact page. Except for its web page, I have yet to find out much about it. Your books might be there for free also.
