I tend to be pretty privacy-conscious and one of the reasons I haven’t up/downvoted much is that here on kbin.social, at least, your votes are very transparent. If you go to the ‘more’ option under any post and click on ‘activity’ you can view exactly how each user interacted with that post. The only time I’ll currently interact with a post is to save it to my profile (or comment like this w/o identifying information.) I think all of this might be a major hurdle to some people.
