Upvotes seem to just federate as likes and dislikes.
That’s pretty cool. Sometimes in an argument there’s that (1/-1) thing going on, would be funny to see how both are downvoting each other.
Yes, after all other servers need this information in order to prevent double voting, you can’t just have servers sending each other information “somebody upvoted this” and also tell when servers are allowing users to vote more than once.
So upvotes and downvotes aren’t actually private, never have been, some servers may display them publicly even if most don’t.
There’s no way that isn’t going to be abused. Some marketing or tracking agency will setup a fediverse server and just collect all data like this for free. Or worse, take advantage of a friendica instance to bombard it with requests for data collection purposes.
Yes, but as long as you don’t reveal your identity, they can’t do much to track you.
They don’t have access to your IP.
Of course, it you’re using the same username over multiple services, or reveal identifying information (which is much easier to analyse now due to AI) they will be able to track you.
Is IP not logged anywhere in Lemmy/ ActivityPub?
Nope just server
What can they use that data for?
It would only be usable data if they could show personalized ads to the users. They can’t.
All they know is that Meldrik up/downvoted this and that, but outside of Lemmy they have no idea who Meldrik is.
I think the issue is that many Lemmy users will think more carefully about what they comment than what they up/downvote, as a comment appears connected to your username but a vote doesn’t. You might decide against commenting on something you disagree with because you don’t want to get in a fight, instead just downvoting it, but if people then know if was you who downvoted can still pick the fight.
Basically the issue is you’re revealing a lot more information than you might initially have realised if you’d have known votes were public all along. Maybe a disgruntled person uses that to dox you, or maybe a corpo feeds all that information into their fancy computer system to work out who you might be, who knows.
The whole concept of the Fediverse as social media is that all the data is public. Stop acting like these servers are giving out private data. This data has never been private, and it never will be. Data like this being shared with any other server is how ActivityPub and the Fediverse work.
I know, but some people assume votes are private.
If you’d only ever interacted with Lemmy and not read up on how ActivityPub works then that’s a reasonable assumption, it’s not like anything (that I’ve noticed!) actually tells you that your votes are public, and they don’t look to be public in the places you’re likely to see!
