The stalking, targeting of married sisters in odd situations, is a ongoing issues in congregations. The elders, that are supposedly there to protect the flock from predatory practises, fail, occupied that they are, with wt procedures.
Eli's sons are alive and well in the congregations.
PS: in my younger years, the 1940, I had a "friend " in the "world" who specialized in preying on married woman, (truly stunned pineapples) , why?. because they offered gratification without liability.
In the case of the disfellowshipped brother, this stalking (a criminal offense bsw) could be a favoured tactic, condoned or approved by the elders, to further humiliate the disfellowshipped person, .--- Clean the "clean organisation" by dirty tactics, dishonoring the family.
