I lived through that period pre-1988 where "approved associates" or "unbaptized publishers" committed a disfellowshipping offense, such as smoking in my cousin's situation, would be shunned as a da'd or df'd jw would be (baptized individuals). In the article I quoted above, the WTS rescinded that policy since "approved associates" or "unbaptized publishers" were not baptized. These unbaptized people would no longer be shunned as baptized jws were that da'd or were df'd. Not that jws would not view them as good association as long as they continued practicing a df'ing practice.
After that unbaptized individuals who had been approved for field service could not do so any more, could not be part of the school, etc.
Quote from above:
As the recent material showed, the Bible requires that such disciplinary action be taken in the case of baptized persons who are unrepentant wrongdoers. (1 Corinthians 5:11-13; 2 John 9-11) Yet, the accountability of an unbaptized person who pursues wrongdoing is not the same as that of one who is baptized. (Luke 12:48) He has not been baptized and thus has not become approved in God’s sight, so disfellowshipping is not appropriate in his case. Basically, he is now a worldly person and can be dealt with accordingly.
