Nice post @Woland.
This kind of activity attracts bad attention to the torrent community and as you said is mostly bad for the artists. I have personally never understood the need to get things in advance at the detriment of quality. As you stated you don't get the final product as intended by the artists or producers. Unfortunately leaks have been going around forever, at least ever since people have been able to purchase camed movies or leaked studio tapes on the streets of NYC or LA. Internet just gave a better medium to access a wider range of users.
