On every thread or post, if you click on more and activity, you’ll get the info.
I personally find this to be a good things, I’ve seen people using downvote way too easily. I like the idea that we need to be somehow accountable for those mechanism.
edit: It could be somehow improved to have an option to let this info only available between concerned users.
edit edit: I think that up/downvote info shouldn’t be public, but kept private between the users involved. we need to address this privacy issue.
In a small community it’s probably fine; but it will get super toxic with big communities or abusive mods.
This is where I see there being an issue as well.
There’s also potential for harassment due to people seeing opposing political opinions. As an example - My wife was once the target of harassment by a number of users on Reddit for days for warning people about an anti-abortion protest that was displaying graphic imagery. Much easier for those kind of people to coordinate harassment of others if they can easily see records of upvoting pro-choice or downvoting anti-choice posts/comments.
