I will admit to having used this site, for books I wanted. These are books I *wanted* to give money to someone for and was unable to, because they are not available as ebooks. And they are all books I have bought pbook copies of.
The books I downloaded are the Jean Auel books and The Moon is a Harsh Mistress, one of my favorite books of all time. In fact I found the site while searching for a copy, any copy, of TMIAHM. I was practically salivating over the thought of giving someone money to have this book on my reader and the only copy available is a pirate version.
Now comes the "pirate's dilemma." These books are plain text, with OCR errors and no significant formatting. I've taken them and gone through them alongside my pbooks page by page and fixed the OCR errors, added back all the italics and bolding, fixed the formatting including the large caps to start each chapter and given each a table of contents. So, what do I do if the publisher actually finally releases them as ebooks? I would have happily paid for them previously, but now I have several hours invested in each book, such that I would probably balk at paying more than $5 each for an 'official' copy.
I think it goes to show how not releasing things legitimately just creates a black market. But perhaps I'm misguided.
