That is valid. It's part of why I wanted to make people know about how upvoting and downvoting works so they can be more mindful about how they use it.
I think it is fine, since likes on twitter have been public. People just need to change their habits on upvoting and downvoting that they got used to when they were on reddit. So need to adjust to how people would go and downvote whatever comment they disliked and move on. Now that stuff is public, so maybe it can help against brigading?
Do you mean being able to see users who upvoted or downvoted you? I'm not aware of where that option is available through lemmy.
I'm sure how to access that through lemmy. When expanding I only see extra options like message, report, block, save, and view source.
You can see the information through kbin but not through lemmy that I know of. So for your comment it is https://kbin.social/m/youshouldknow@lemmy.world/t/82174/YSK-You-can-view-upvote-and-downvote-information-through-kbin/comment/347422/favourites
It's who upvote and who downvoted that is available through kbin so for you on this comment
YSK: You can view upvote and downvote information through kbin
Why YSK: your upvotes (favorites) and downvotes( reduces) are public information.
If you are browsing through https://kbin.social/ or whatever just click on "more" then activity.
There you'll see info like boosts, reduces (downvotes), and favorites (upvotes?)
Works with all instances for lemmy or kbin material
