Of course it's fake! Lighten up everyone and don't be so serious - it's simply a little bit of spooky entertainment. There is even a disclaimer at the start of each show actually telling us that it's for "entertainment only", has no-one spotted this? The programme doesn't claim anything else. It isn't real, it isn't intelligent, but is interesting anyway for taking us behind-the-scenes of renowned (often historic) haunted locations that we would not normally have access to. Try to take it in the spirit (no pun intended haha) intended, and enjoy a little lighthearted, spooky fun :)
