I actually like the idea of being able to see how many upvotes/downvotes came from specific instances much more than seeing the actual users. It would cover some of the positives mentioned in the github discussion:
-Could help fight bot and multiple-account voting (if we assume that people who make multiple accounts do it on the same instance)
-Could help identify voting-patterns from specific servers (obviously)
And then if something looks suspicious, the admins can already see who voted, so they could check out whether some user is abusing the mechanics.
I find that this approach might be worth talking about, but making user votes visible to all seems very unnecessary.
I never heard about the tildeverse before, sounds really interesting. How does one choose which tilde to join, though? It seems to me like only cosmic.voyage has a specific theme, while the rest only differ in the OS running on the machine. Or are tildes just there to host your account, while all the interactions are done via irc?
