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 dsiagree that transparent upvotes are an issue. In fact i think it’s a powerful feature for community to self correct and resist astro turfing.
On reddit votes have become meaningless because they are not 1 person == 1 vote and its completely astroturfed. You can literally got to buyredditvotes dot com (not real but real ones are very close just google it) and stuff any post with votes and nobody will ever know.
Transparent interactions are key for community health even if behind anonymous nicknames. So all interactions should be transparent.
My only issue is that many lemmy instances are blocking popular VPN services which is very dangerous. I understand the bot argument but (even though residential proxies are dirt cheap these days) user safety suffers hard here.
