I recently learned that voting on lemmy is not anonymous. Anyone can get information about who has upvoted and downvoted a post or comment.
In combination with your IP, this is a massive privacy (maybe even physical security) risk. Also, people can target you for your votes.
Sadly, this is something where I would prefer Reddit over Lemmy. Big tech scrapes data from both places anyways, at least Reddit is safe.
On most social media the voting is public, see Facebook/Twitter likes. Hell back in the days of forums you could usually see the list of users that liked a given thread in most of the forum software I ever used. Reddit was the anomaly really
I think piefed has a feature where your votes never leave your instance, so are not exposed in this way (but obviously only appear on your home instance too)
Agree that it should be clearer to people coming from Reddit that that’s how it works though.
The thing is they make it extremely clear that votes are public by letting you see who voted right next to the button.
Lemmy hides this feature and most users don’t know about it.
