At the time I left it was important to me to disappear. I did manage to have my Publisher Records cards forwarded to a family member including the letter of introduction. I was however in relative good standing at the time which facilitated the deception.
I still have my cards and I did a successful disappearance. However later when I got involved in Child Abuse issues as an advocate and appeared on TV and testified in court the resulting shunning still happened even tho a formal Committee has never been formed against me.
So disappearing while still in relative good standing is fairly easily accomplished (I've helped a few people do so). Getting reinstated so as to then fade is a lot more difficult but not impossible. Posting the exact details of how it was done is rather self aggrandizing and threatens the success of the initiative but people make their choices.
