What you’re telling people to do is a manual version of mother-slave accounts. This method only works at scale, but in order to scale this you’re probably botting (scum, how dare you!) or you hire multiple people to run accounts which most small businesses cannot afford. This method was popular a couple years ago, but the amount of backend costs are no longer practical for most. These days you’re better off just paying for shout outs and dedicating all of your time and effort to your real page.
