Currently, each thread has the “Activity” link that shows publicly everyone that upvoted/favorite a thread. This is counter norm to many coming from Reddit and newer folks that expected otherwise. I think hiding the list should be high priority in next feature update(removal?) to encourage frictionless upvoting behavior.
Case in point, NSFW threads are starting on kbin now, cross that with micro blogging that may involve people using real names, this creates unexpected personal preference being exposed.
As a option, Boost feature may still left to public view.
Anonymity is important. Let me know if I misunderstood how this works.
As another user pointed out, what about an LGBT person wanting to upvote something but not feeling safe if someone knows their username? Or a woman living in a place with abortion bounties wanting to upvote something about how to get help, but being afraid to?
Or someone with an abusive spouse who might read between the lines (correctly or incorrectly) of what you upvote/downvote and get angry about it?
There are a lot of highly significant real world ramifications to having your vote history publicly accessible. Losing your job and life or death consequences far outweigh the online voting system considerations.
The possible problems caused by this FAR outweigh the possible benefits. People are just not thinking this through enough to see how badly it can go.
