My bad, sorry. I was under the impression that the way that the second chance pool worked was that the original was boosted instead of a copy being created so it seemed like a duplicate.

(other mod here) - not your bad! our complexity :) - usually it works exactly as you described, but when the post is older than a few days we have to do it the other way, by spawning a new post. The reasons for this are mostly technical and boring.
