Ask HN: Why can I only upvote (and not downvote) old comments?
In recent threads I can downvote comments but for old threads, I can only upvote comments. Why is this?
- wmf 11y agoIf someone unfairly downvotes an old comment, no one will notice and correct it. This would allow you to drain someone's karma by systematically downvoting all their old comments. So HN doesn't let you do that.
