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.
I’ll downvote something if it is irrelevant to the community at hand, or if someone creates a community specifically to bypass community blocks users have made. We don’t need 10 communities about the same thing, and users should absolutely be penalized for making superfluous communities to evade community blocks.
