If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that’s for the future of us all.
Maybe we’ll move to a system where only upvotes from that home’s instance matter. After all karma is meaningless anyway and is just used for short term discoverability, maybe kbin1.social doesn’t care how kbin2.social votes on kbin1.social threads (or any lemmy example instance)? If you subscribe to kbin1.social then you hope that they will upvote their content appropriately the same way you expect them to self-moderate appropriately. Dunno, just thinking out loud
