Not so rare now. Not for copyright material be it video or TV material. This spam type has started to come in strong for such material. Almost as though there's preset keywords for both tv & video material to grab the spam engine's attention. Such a list wouldn't take too long to put together. It seems to have happened gradually which suggests an ongoing process of adding to this list by the overpeers which perhaps are the ancestors of the present gangs/thugs/overpeers/r*aa/child rapists.
