On JW.org in Frequently Asked Questions it explicitly says they do not shun those who don't preach or no longer attend meetings.

Simply go to https://www.jw.org/en/jehovahs-witnesses/faq/resign/ to read this statement: What if a person no longer preaches or attends your meetings? Do you view that person as having resigned?

 No, we do not. Resigning, or disassociating oneself, is different from becoming weak in faith. Often, those who for a time slow down or stop in their worship have not abandoned their faith but are suffering from discouragement. Rather than shunning such ones, we try to give them consolation and support. (1 Thessalonians 5:​14; Jude 22) If the person wants help, congregation elders take the lead in providing spiritual assistance.​—Galatians 6:1; 1 Peter 5:​1-3.

So by saying "Rather than shunning such ones..." they imply that they DO shun for disfellowshipped persons and those who have resigned.

This will be part of the book I am writing, and if you have a JW shunning story I would love to include it in my book. Please DM me if you have story you would like to share.
