I tested it out. I think making it expensive makes sense.

We tell you when the link is a duplicate of what someone else has posted. You can demo it by putting a link from the front page in the link form.

We don't prevent you from doing this however. Plan is just to make it very expensive to repost a link within a week or so.

might be something for @k00b to add to his to do list, if not already on there: an autocheck before posting a link to see if someone else already posted it.
