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.
they advertise/tout you can use your account on multiple devices, but that is definitely not true.
The system they have for account sharing is a little strange, at least with the family plan, where instead of having everyone on one account (like what netflix does/did) you instead have to link different accounts to the one that pays for the subscription.
As far as I know the joke is based off the flat earth conspiracy which says that Australia can't exist and therefore must be on the other side of the flat earth
