Probably better to post in the github issue rather than replying here.
Lemmy actually marks votes as private for federation, but it seems that kbin/mbin ignore that.
Ahh, didn’t even know there was a flag for that. I don’t suppose you could link to the relevant w3c or FEP for it?

Next time try reading the spec before asking.
How about you assume less? I spent 40+ minutes looking for this here, here, here and here and I’m already fairly familiar having done work on two other ActivityPub based projects.
In addition public-addressing (or the lack of use thereof) in no way claims to achieve what you’ve stated - which is probably why it’s not the answer to my query.
