Zaps are amazing for easily transferring value, but I'm not sure what they are a good signal for.
People looking to achieve high follower counts with little effort can do zap4follow scams, basically buying followers, and giving them a large amount zapped. Anyone can make multiple npubs and round robin zaps to up their numbers. It's easy to game the system.
What could one learn from this information? How could this stat be used to indicate community involvement?
