The pyramid thing is creepy, because it seeks to exploit friendship bonds. And usually only for the benefit of the company, the seller most often is being suckered into losing money as well. I wouldn't really consider someone doing your last two things there to be doing something friendly, those are self-interested actions and I would treat them with suspicion. The first three though, sure, those are friendly actions. Their utility is variable, but they aren't motivated by personal profit.
