Disfellowshipping has changed over the years:
A personal friend of mine was DF'd for a time about 15 or so years ago. At the time of her DF she had kissed one boy and smoked one cigarette.
Today I know of unmarried sisters with children, in one case - 3 children from 3 different men - and these have never been DF'd. The same friend of mine mentioned above could not believe the way these "sisters" were "dealt with" vs the Sanhedrin she faced as a teenager.
I guess Jehovah has become more politically correct over the years and/or is afraid of getting sued. I agree with the general consensus that we personally decide whom we shun should they blatantly continue in sin. Jesus showed love and so do we. We can forgive their sin against us, Jehovah forgives the sin against Him.
No human can sit on Gods throne and speak on His behalf. This presumtuousness amounts to self-proclaimed inspiration as a prophet.
