We had a family in the old congregation that got disfellowshipped for demonism. Mother, Father and Daughter - all at once. The story was that they were going to some native american "witch doctor" medicine man. He was giving them some weird kind of herbal tea stuff for all their psycho-babble percieved illnesses. The congregation committee found it out when they tried to promote it to some other people in the local halls - they got called on and told to stop it, but they really believed it was helping them and would not quit.
So, in effect, three people got disfellowshipped for being gullible hypochrondriacs!
Although I have posted this one before (under threads which took up the issue of congregation committees who took up an axe to grind on some person who was not popular).
But, it seemed to belong on this thread, too. The funny thing was that no real paranormal events were reported to be taking place - the issue was that they just would not do what the congregation presiding overseer told them to.
