That could probably go in the primer page or about page, some sort of encouragement to vote based on the quality and content of a comment or post, and to restrain from voting simply because you agree with the sentiment.
once more with feeling: I've got most of these people ignored so I can just sort of go "libertarian circlejerk" and move on. I'm all about libertarians having their place to circlejerk and if they want to encourage and discourage and debate and disseminate and cheer on and shout down that's entirely their prerogative. What you've got here is a viable mechanism whereby it doesn't impact me. The system works. Don't fuck with it without a damn good reason.
Every time you share a post or comment, you are instead linked to a lengthy remonstration reminding you that even the smallest actions have far-reaching moral consequences. And a warning that upvoting a comment has the same legal repercussions that being accomplice to a crime carries. Or just this.
