Kazaa Lite is just as vulnerable as Kazaa to those who wish it to be.
They've sending subpoenas to everyone downloading that they can, even people downloading legit files, and porn. If they subpoena you, they can take all your pc equipment as evidence, and all they need to find is one file that isn't yours, or free. Chances are, if you're on Kazaa you have a file like that, I would guess that is their line of reasoning.
