My guess is that this is a comment by the same user who posted the article. In a few minutes after the comment appeared (when I saw it), article's Karma was at -1, and the usernames used to post both the article and the comment were deleted. Perhaps the user didn't like the downvoting of their article and reacted by deleting their account.
