At one point an unbaptised publisher was called an "approved associate" and could be dealt with and disfellowshipped as per a baptised individual. Then the noolite arrived (probably by legal pressure) and it became that an approved associate was now an unbaptised publisher and couldn't be df'd but could be removed as a u/p. They are then viewed as of the world and thus bad association for social purposes, especially by the rightwingers.
But ... if the u/p is consider a danger then marking and words in ears goes on and they can virtually be ostracized depending upon who they have upset.
Now if you just don't get baptised and do nothing "wrong" you get to about 18 (in England) and people start to wonder why you've not jumped into Jah's ark and as you reach 20 the gossip machine goes postal and you are viewed as unworthy by the righteous overmuchies but still befriended by the rebels and the faders and the eccentrics and your family splits into two camps of "pharisees" and "weak ones" and they treat you accordingly.
If you are hardnosed about it you can tread the fine line and fade from this fence sitting position or stay in it unscathed but you only need a couple of nazi elders on the body to apply pressure and/or formally boot you into touch and make life difficult for your jw relatives.
