It's actually in the rules that you're not supposed to post comments stating the rules. (Whoops!) So these stories get posted, nobody can post in the comments that the story isn't proper, and the submitter never finds out that he's doing wrong. Especially when people start upvoting stories that break the rules. (Again, because they don't know the rules.) Most people don't read the rules for a site before they start posting stories and comments. Even if you try to force them to. That's human nature and should be taken into account when designing a site like this.
