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’s why redundant communities are important. Admins and mods make different decisions and heavily shape culture in the community.
Many don’t like it but I think it’s a beautiful feature of the Fediverse.
If there are redundant communities then the communities are diluted and less active.
Double edged sword
