There had been a trend toward being lax regarding DF'd ones at the hall; that is partly why the WTS cracked down in 1981. Note this quote from a 1981 WT. Starting in 1981, the WTS became more rigid and unloving in this area (due to the apostate scare at Bethel as well).
w81 9/15 pp. 29-30 If a Relative Is Disfellowshiped . . . ***Consequently, Christians related to such a disfellowshiped person living outside the home should strive to avoid needless association, even keeping business dealings to a minimum. The reasonableness of this course becomes apparent from reports of what has occurred where relatives have taken the mistaken view, ?Though he is disfellowshiped, we are related and so can treat him the same as before.? From one area comes this:
"One person who was disfellowshiped was related to about one third of the congregation. All of his relations continued to associate with him."
And a highly respected Christian elder writes:
"In our area some disfellowshiped ones with large families have been met, as they enter the lobby of the Kingdom Hall, with a fanfare of backslapping and handshaking (even though the disfellowshiped one was known by them to be still living immorally). I feel a deep concern that those who have been disfellowshiped need to see that their course is hated by Jehovah and by his people and that they should feel a real need to become genuinely repentant. What will help these disfellowshiped ones to change when they are continually greeted by all in their large families who know of their practices?"
