My wife and I simply faded on our own and have never been in any kind of "elder" trouble but I know that if we showed up at a new Kingdom Hall and started attending again, they'd want to know what the name of our former Hall and they'd call our former Elders and get our "file" and get the" Low Down" on us and they'd hear someone else's version of our leaving JW story. They are very suspicious by nature and a bit paranoid about new ones. They have long memories and everybody knows everybody and elders wives know more than they are supposed to.
I've been to Kingdom Halls in entire different countries and have met people who were related to or knew the same people I did and who are quite ready to talk about them. There's no such thing as a fresh start or a "do over" with JW's...someone will always be looking at you with knowing eyes.
