Hmm, so federated downvotes from Lemmy are public now on mbin, not just local downvotes and federated upvotes. Interesting. Does mbin-mbin downvote federation work? kbin doesn't federate downvotes to you. (I checked -- for science! -- but switched back to an upvote afterwards.)
i would expect mbin->mbin to honor the federated downvotes, assuming the newest version of mbin 1.30.current. definitely could use a good test though
not sure who knows or not, but the 'bins also publicly make available a 'reputation score'. aka, karma. so even if you think youre living a karma free life over in lemmy, its calculated elsewhere.
