I think people who are downvoting this comment are projecting what I meant by "so simple." There was no judgement on that statement. It was more an observation relating to that it could happen to anyone, and that they were "lucky" the person who got into their system wasn't really malicious.
Yes; upvoting just puts the better comments nearer to the top. Downvoting the fluff comments (with the minimal "effort" of a click while you read past) actually greys them out, which both discourages people from posting fluff in the future (with a minor karma hit), and makes it obvious to other readers that they've made it to the end of the real comments.
