101% absolutely.
Confidentiality is a beautiful thing. Breaking confidentiality is nasty. JW elders are generally nasty and (not all) but the majority are 101% guilty.
Every 90 days I would gather agenda points from the elders on our BOE and inevitabily would have to ask several times a year "Brother Shitstirrer is this matter a result of your prayerful thoughts or input from your wife or family member?"
Fast forward to BOE meetings, including the last one I chaired in 02-2018. One elder started his concern with "I was talking to my wife last night and she is really concerned about sister opinionated who got in the face of sister bestlife ever in the Kroger parking lot and now brother bestlifeever is threatening to beat the shite out of sister opinionated" Ahh, so your wife asked that we discuss the matter. WAIT! Time out brothers, how about we talk about something much more pressing that brothers shitstirrers wife is concerned about, and that would be Brother Canthink4himselfs new beard!
As far as between elders...I call it "back channeling". If I had a dollar for every time another elder wanted to 'have lunch' to discuss a matter behind other elders backs and sway the feelings of others......gosh id have enough money to pay cash for all the PTSD cult recovery psychiatrist sessions i now require.
To this very day, elders are trying to "connect dots" as to where me and my family are, what we are doing, what % of meetings we are attending (which is -0%), are we attending in other congs, what are we talking to others about, are we associating with disfellowshipped people, ect.... Ha, my kids are prepared to offer 1 Thessalonians 4:11 as an answer to anyone who confronts them about what they have "been up to".
Toward the end when i realized the true demon of breaking confidentiality, I enjoyed throwing out various wt.org bias statements and watching the rats go to work and create divisions. SO much energy is spent spreading REINTERPRETED information among JW bodies of elders which filters right down through the pioneer car groups and eventually into the minds of the rank and file.
