Votes being public is one of my main turn offs of Lemmy. Anyone can host their own instance that federates with everyone and peek inside the database and see everything you’ve ever up voted or downvoted. I have personally done this just to confirm my suspicions that it is possible. I don’t vote on a lot of things I otherwise would because I don’t want people making assumptions about me. For example, if I see a copy/paste bot spamming a pro trans comment, even though I agree with the message, I might want to downvote because it is a spam bot. But I’m afraid that if someone sees that comment in a list of my downvotes without any context, they will incorrectly think I’m transphobic.
