I opened @leprechaun/transfers and @vempromundo.pob/transfers. My delegatee voted on this:
@madstacks/community-litter-picking-drive-earn-pob-and-save-the-planet-week-3
He received 1 POB curation reward but I got nothing for this.
By comparing the curation rewards of the delegatee and the delevator you can observe whether rewards are absent in the delegator that are earned by the delegatee. In the case of Hive Engine tokens, there is no protocol level monetary reward for delegating. I know this isn't Hive but I am more interested in this topic through the lens of POB.
I leave this as a potential methodology for experimenting. We need to find someone with delegated Hive power and the corresponding delegator. Then we can look at the curator rewards. If it's like Hive Engine, there is no reward. I'm convinced that the essay is wrong until I can be pointed to a pair who have a delegation from one to another a week from the time I see them or before, I will work under this belief.
