This is how it works: if a post was previously posted less than 14 days ago, user will get an error with a link to the most recent repost. On the other hand, if a post was previously posted more than 14 days ago, the post will be submitted like a regular one, but a comment that contains the following message and link to the original post will be automatically posted by @Pauline. > "This post has already been submitted in this sub more than 2 weeks ago.
