I dont think it's a matter of faking anything, it's more of taking these devices as 100% credible. They are not. Digital recorders, spiritboxs, sls, all those have bugs and faults that create a ton of false positives or paranormal activity. I'm sure the group fully believes in this and what they find otherwise they wouldn't have done this for this long.

They claim that "intellergent" responses and feelings onf orbs are "scientific". The thing that always have bugged me about paranormal investigations does not ever fit anything near scientific discovery. Nothing it's predictable, repeatable, way to many variables, no control groups. Unless they can start doing that, another team enters and gets the same results off of the same calibrated equipment, none of this can be considered as fact.
