@dimakoles : the fact is that your questions can't really be anwsered, because it is not something that happened to the past (right?) and the description of method and results will lead to this:
: "So, they did like tis to protect their products, lety me try.. This!now, Their protection isn't valid anymore, let's upload this to thetipiakbay"
Also, an exemple can't really be explicit, since it concerns legals issues.
the fact is: you can't really win against piracy, you just don't lose too much, and more you say about it, more you let it reach you
Game design is all about decomposing the core of your game so it becomes simple instructions.
