Sounds like you are employing a reactive, defensive and antagonistic approach to eBook “piracy”. Which puts you into the very position you described - at a loss, angry, and frustrated; instead of fuelling your sales and playing a direct hand in your success. Unfortunately I don’t have the article on hand, but about a year ago I ran across a description of how an author _dramatically enhanced_ his sales by leveraging eBook “piracy” in order to drive people to official channels.

Yes, he actually released his eBooks for free onto the piracy sites - with a twist: he included the entire first portion (quarter or third, cannot remember) of the book, gave info on where to buy the full copies (with zero recriminations - just the facts!), and then repeated those same early chapters to plump out a fully-sized eBook. He then flooded all the file sharing networks with this copy so as to make it difficult to find legitimately complete copies.

The entire first quarter or third was used to get readers heavily enough invested into his novel to _want_ to run out and buy the official copy -- he _justified_ the effort and expenditure to his readers, and they responded (mostly) positively by actually doing so!

Granted, there was a lot more to it than that, but this was the basics, and it pushed a lot of people towards not just his eBooks but also his physical sales. And there are probably many other strategies out there as well that utilizes the “piracy” platforms to your benefit instead of leaving you tilting impotently at windmills.
