On the thread about older women pirating, people discussed at some point about the the websites where you get the ebooks from, and how do you know if the site is reputable or not, how do you know if a free book is free because there is a special promotion by the author, by the store, because it is part of the public domain, or if it is an illegal copy. I think that questioning the source of the file should be a good idea in all cases.
But I don't think that people would really do it.
