Yes, I also use unfollow/follow as well mute/unmute to manage my feed in some apps because they don’t have good tools otherwise. The “zap mining” behavior by some, however, is of concern to me because it is scammy and can be harmful in a real way, and it is fairly obvious once you look closely enough at the accounts doing it. Whether they are actual bots, or just one or two people with dozens of alts that they switch between, I don’t know. But they’re clearly not being good people.
