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.
It literally can’t be private, just from the way Lenny works. You can’t have it all. You could in theory make it less visible, but that would be a false sense of privacy as it would be possible to do get the information with some effort. Just having it be fully open is more honest and makes no claims it can’t keep.
It’s social media, even if federated. On Facebook, tiktok or whatever they are also not private btw: maybe users can or can’t see them (I have no idea), but the company behind the platform certainly can and will use it for advertising to you and for what else to show you, making you the product.
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.
