Not going to lie, I got banned so I made my own World News Community. This community differs because there’s no silly bot, I’ll happily listen to the communities voice, and we’re a bit more lax on rules policing.
Feel free to come on by and comment. I would love to foster a News community that’s active in discussion.
Your actor (

I’m not completely sure, and I just took a quick look through the code and protocols and couldn’t find the place where vote activity signatures are validated. But I swear I thought that all ActivityPub activities including votes were signed with the key of the actor that did them.
Regardless, I know that when votes federate, they do get identified according to the person who did the vote.
In practice, you are completely correct that the trust is per-instance, since the instance DB keeps all the actor private keys anyway, so it’s six of one vs. half dozen of the other whether you have 100 fake votes from bad.instance signed with that instance’s TLS key, or 100 fake votes signed with individual private keys that bad.instance made up. I’m just nitpicking about how it works at a protocol level.
