Once again, I have to ask where is the solid proof? There is no actual proof that any of these people are frauds at all. Just skeptics that want to dismiss something they don't believe in or agree with. Which is shallow as far as looking at all possibilities.
Not gonna repeat myself here, but I will say I am willing to see direct proof that exposes Zaffis and the Warrens as "frauds". Such monumental claims warrant monumental proof.
This has been discussed in numerous topics here, in detail. I am not into repeating myself anymore on these things. It is always a repeat about once a year or so. Same old stories, same old discussions, all of them carbon copies of what has been discussed ( here and other places ) numerous times all ready.
One clue for you.......The Amytiville Horror was not a true story !!!!!!!
Anyway, whether I wanted to go through all of this again or not, saying " psychics " and " ghost hunters " are valid people to use as proof and more importantly, using them as credible for " documented cases ".......That is a joke.......No bias there huh?
As said, Find some from a University, a registered journal would be even nicer.
By the way, welcome to UM......
Use the search tool here, you will find a ton of topics as I said about frauds like them, and them.......
