BIAHI:
I believe they don’t just avoid certain ex-JWs because they are afraid of what that person knows. And they are right because we know plenty.
They are also unlikely to contact ex-JWs they can’t exploit materially!
The religion is more likely to want to reactivate ex-JWs who they remember as being an ‘asset’ who opened up their home, entertained, served food. Maybe they had a skill and did work for certain JWs for free: fixed cars, prepared taxes, cut hair, etc. The Witnesses are Users of the worst sort and anybody who was generous would be sucked dry.
Positive accomplishment: Peace & Quiet. I was criticized as not ‘spiritual’ because I worked, didn’t ‘pioneer’ and certainly didn’t do favors for the Users.. I doubt they’d contact me.
