At least with link repetition I can quickly see whether I already read this and decide to ignore it. But re-posting an old, cancerously-grown comment with a new first paragraph is just mean and lazy.
Just rely on the upvoting system. If people think it is relevant, they upvote. This means things will only show up on the front page if enough people are interested (ie it has been long enough since it was last posted).
I believe that's wrong. From what I've seen, I think that that time is also a factor. After some amount of time, you can repost things with exactly the same link and title. And I believe that it's deliberate (the posts are likely to be new to many people since the population turns over to some degree after x amount of time).
