This will probably go the way of Aimster. IE: You can't play dumb to shield yourself while knowingly assisting copyright infringement.

The court held that in this case the users of the systems were the direct infringers, these who are ignorant or more commonly disdainful of copyright and in any event discount the likelihood of being sued or prosecuted for copyright infringement, however companies such as Aimster that facilitate their infringement, even if they are not themselves direct infringers can be liable for copyright violations as contributory infringers.
