Like the title says, if you want to upvote something on KBin, you should use the Boost link, not the upvote button (Why? Don’t know…)
The upvote button doesn’t seem to do much, but Boost accomplishes what Reddit’s upvote did. So if you’re looking to encourage a post, use the Boost link.
I don’t know if you’re being sarcastic or not, but just in case, that’s the point of a boost. You’re boosting its noticeability. It’s not supposed to be private
