If you want to get technical, JWs have not "disfellowshipped" anyone publicly in several years. They stopped saying,
"Joe Blow has been disfellowshipped." years ago, and changed it to
"Joe Blow is no longer one of Jehovah's Witnesses."
So lucky Mr. Blow could actually walk up and say to a Dubb, "It was never announced that I was DFed, you can still talk to me..."
