This paranoia could actually be used against the bOrg. Because everybody is to suspect everybody else then mention to one of the Elders the name of a specific person in the congregation, who you think is going to be the next to leave for apostasy.
You do not need to give any details, its just that you have a feeling, no more. You can do this if you attend meetings or not. If you do not go but are suspected of apostasy anyway what you say will have more weight.
This should really get the witch hunt going, and help some to wake up.
