I was thinking about it, how I can figure out who zapped on my posts and / or comments...because that would be fair from my side to "re-zap" them.
Hmm, but I think it's about making the cake bigger = more fun, not just returning the cakes ( favor ). 🤔
however, there are some little hacks you can tell tho if you are paying attention, like some stackers have their own unique zapping codes e.g., @Undisciplined you can even read about the zapping meanings if you are paying more attention:)
