Techdirt looks
at the problem of copyleft trolls, and those who target users of
Creative Commons materials in particular.
However, in the end, they are still licenses, and those licenses
are still backed by copyright — which means that if you don’t
abide by the specifics of the Creative Commons license, you could
very much be liable for copyright infringement. Enter the copyleft
trolls. They search for those using CC-licensed works, but not
following the exact terms of the license, and then resort to the
typical copyright troll shakedown game.
