My recent bug question, Upvoting/downvoting a post more than once doesn't display an error, wasn't taken too well, implying that the 'double upvoting' error* only applying to comments, and not posts, isn't actually a bug.
This question is tagged as discussion, because I want to know why. Why is the error only triggered with comments, and not posts?
The "'double upvoting' error" refers to an error triggered when a comment is attempted to be upvoted twice in one session (i.e. by upvoting it in one tab, switching to another, and upvoting it again, without refreshing).
