Strange Encounters

I tried to watch "Haunting" on the Sci-Fi channel tonight. (You know, they interview families who have lived in haunted houses, had encounters with poltergeists, etc. I thought it would be like "Unsolved Mysteries," and "The Office" wasn't on.)But, tonight, the family they interviewed would only be on the show on the condition that the producers would "protect their anonymity." They were in the dark, and you couldn't make out anyone's facial features.And, I still don't understand - protect their anonymity from what? The ghosts? Do they think the dead confederate soldier in the basement will retaliate because they "testified against him"? Are they worried about being sued for slander by spirits? If there are ghosts, would they even watch television?It just doesn't make sense, and, truthfully, I'm relatively speechless.
