As a copyright holder, that's not my problem that 1 in a million decided to upload some questionable copy of my work to a publicly accessible pseudo-sharing site that violates my copyright over and over and over again.
If you upload it to MU, then cry to someone else when that same criminal enterprise gets shut down and you lose the one copy you had.
Your right weren’t violated. Mine were.
Anyone crying about this is just playing a victim card here after making a bad decision. Or can't come to grips with reality after assuming that since copyright infringement is so easy to do, it must not be a bad thing to do, and it must be part of your entitlement.
