I did a search under my name and found six of my KDP and Pubit ebooks with copyright listed as available for free! I immediately directed them to remove these and any other ebooks of mine from their website. Their add has several grammatical errors, and they claim to ship you free ebooks from Amazon.com..
Thank you Elaine for bringing this situation to everyone's attention. I suggest that Amazon.com should also be notified.
Haven't gone there yet but have found ,mine on such websites before. Have you guys clicked one of the claimed "free" eBooks all the way through? I ask because the times I saw mine on these, they actually only have a blurb-length portion and then it ends with them giving a link as an affliate via to Amazon or another bookseller.
Try clicking one through and see where it takes you, to see if this might be the case.
