No they are not going for the big downloaders, they are going for the big uploaders. The giving away those files is the real illegal part. So just go into your options and turn off file sharing then you have nothing to worry about. As for me I use mIRC, it's amazing, a little more complicated but once you get it you'll love it. dl it at
www.mirc.com then go to
www.ircspy.com to find whatever files you want.
