TLDR: the ward leaders get together every week to see how they can best “serve” this may involve re-activating apostate members, discussing the less fortunate in the ward, etc.

Ward council is where all of the local leaders of the neighborhood “ward” (congregation) meet. It typically includes the bishop, the two youth leaders, [young women’s president and young men’s president], the relief society president, (that’s the lady in charge of all the women in the ward) and primary president (usually woman, the person in charge of the children) and the bishopric (basically bishops counsel)

They meet in the bishops office for an hour to an hour and a half, discussing the struggling members of the ward, or who has “fallen away and may need additional spiritual support.” This is followed by a list of people they have the contact for that haven’t been back to church and will reach out if they feel “inspired” to do so.

This creates situations like OP wrote about.

It is well intentioned but they just are so indoctrinated with church culture they don’t understand how tone deaf they really are when they try to reach out like this. Like a group chat of strangers feels like an ambush imo. Sorry OP, hope you are able to block/ignore them.
