There is nothing in JW rules that prevent elders having occasional communication with DFed ones. In fact they are told to catch up with them once a year.
That has actually changed now. No longer do they make contact with DF'd ones. Only if they should happen across them in their "serve us", and if the DF'd one is either known to them or informs them they are DF'd. Then they just give them the Return to Jehovah pamphlet. This told to me personally by the local COBE. Can't have those oh so important elders wasting time looking for "lost" sheep like the shepherd in Jesus parable now can we.
Now why am I FedUp?
