nowadays, they just announce that "so-and-so is no longer one of jehovahs witnesses", so there is a lot of wiggle room in that wording. technically, you may not actually have been disfellowshipped but just "DA'd yourself by your actions" (a phrase my family used on me for years).this would get them around the technicality of actually talking to you, and the end result would be the same anyway. actually, if they don't technically DF you, but just use the "DA'd by your actions" approach, i doubt you'd have any room for appeal either as you would in a regular DFing case.
