I'm not an elder. I've been a fader for 34 years. No elder from my congregation or any other has ever tried to contact me in any way. I know I'm not DFed because my dub mother still speaks to me.
From all the varying accounts I've read here, it's a roll of the dice as to what elders will do when you stop attending meetings and attempt to fade. Some elders will follow you around like a hound on a scent; others will act as though you never existed.
I don't think there's an official WTS protocol about how to handle faders, other than a few nebulous "shepherding" suggestions.
Ex-elders, what say you?
