Couldn’t you have the main instance take care of it? I don’t exactly know how activitypub handles votes but if they’re reported back to the users home instance it could be calculated there.
For example if I had a reputation of 12 and I posted on a different instance and got enough votes to get 1 extra reputation those votes would be reported back to my instance which would update my rep accordingly.
Yeah that’s fair, but without some form of centralization I don’t see how you establish trust. Unless you have every instance scan every users history but that would be pretty inefficient
