Do you know how many real paranormal researchers are, or have been professionals actors? About as much as were circus clowns.
The reason why so many actors are cast in these fake paranormal research shows= So they can illicit fake reactions, if real things were being experienced then actors and their inauthentic reactions would not be necessary.
By the way, the point of this post is not to state old news, but to wake the few people up who knew facts like these and still think the show was real, it's not, you're simply gullible, use your brain occasionally.
