I think it is an interesting idea. It may actually work based on each cong and what those guys do.
You would think is someone did not want to be a JW anymore they would think "fine, one less person to have to watch like a hawk", but instead it is as if you were married and you went to your clueless spouse and said I want a divorce. Come on, just let people go. They will go quietly if they are allowed to go. However, they are just shooting themselves in the foot by acting like @$$es trying to track everyone down that says anything anti-JW.
