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.
That may be true but it makes the Lemmyverse much more robust in the long term.
I don’t care if I have to subscribe to multiple similar communities or see some posts multiple times, as long as not one or just a few people control the whole discourse.
