This person internets. π
Without a common authentication scheme that every instance checks against... Probably anyone can do it. I don't know how you'd even approach this. Signed messages via GPG with a common pubkey host? Some blockchain scheme for authentication that obviates the need for a central host? I've no idea.
Can't someone talk ActivityPub directly and do this? If the instance is responsible to authenticate the users, the instance can just directly talk ActivityPub to the rest of the network and tell it users and votes on the fly, without even Lemmy running there.
More like a side effect of sending data to third parties. Whether it's email or messages, you can't control what happens with that data on the other end unless you control both ends. But then you're talking to yourself.
Maybe they meant they need to setup their own instance in order to figure out who's downvoting beans.
Err, up/down voting is just a quick way to agree or disagree. If one is voting because they feel they can't stand behind their opinion if they expanded it in text... I don't know what to tell ya.
I'll be damned. I had no idea Conde Nast owned it. That said I can see a more recent injection of $150M by Tencent too.
It's already indexing it.
