It looks like a reverse of a trend I have seen of people understading the details of selectively hiding information from others and using it for manipulation. ,,Show to group of people except X'' is manipulative behaviour (instead of kicking out the person from the group, or in this case not sharing publicly what's not public). On instagram I have seen a lot of these things, for example posts, stories, archived stories all have different very strange behaviours that only people to take the time to understand (more manipulative people) use, which makes people more manipulative in itself.
