Sorry, I don't have time to read all the replies!
In as simply stated as possible! They don't want the individual to have any kind of proof of how they are treated!
Anytime really know the total story about someone's case, and they are df'ed. If you ever say something about it to an eldub, they will pretty much respond with. Well you don't know the whole story! Or there's more to it!
In my own case, they never told me I was being invited to a JC meeting, nor what the charges were! I went to just clear up a few questions, and walked out twenty minutes later df'ed! I had no ideal that was even a possibility! Sometime later when I got my head straight, I ask questions of two eldubs, a week later they told me, that all the notes from it had been destroyed! So I started pushing harder! Two weeks later, they called me to the room! Well magically, the notes had turned up! In the notes it said I had been told it was a JC, but also of the charges, and how I had confused! None of witch were true! I remember the idiot taking notes thought he was a stenographer, and used a green stenopad, the pad they supposedly had the notes on was a large yellow legal new legal pad that had not even had a second page turned, they wouldn't even let me see what was written on it, much less read it. I got a quick glimpse of it as the as_hole was putting it back in his bag, it was blank! Lying power mad Bastard's! If I had been allowed to record it, or have someone with me, to tell the truth, the as_holes couldn't have gotten away with it!
