Hope the files you're dwnlding are not copyright which can be traced via your ip. Your ip supplier can of course monitor such things. Your reason doesn't really stand up well.
The folders listed in your LW Library are either incomplete or shared! That's it! Sharing actually improves one's chance of connection to other peers. So if you can't play from your library, tough luck. Such people who don't share are known as Leechers!
