Lately in april they presented a device referred to as Rights supervisor, where noted manufacturers has the rights to observe and claim their copyrighted videos uploaded to facebook.

Copyright house owners can request deletion of the detected pirated movies or add exception for few manufacturers in some cases.
So what’s the hack?
