If you go to the "lists" page there is literally a "noobstories" page, because someone deemed that that would be an interesting filter for some people to explore. What's the point of posting if you're a noob if you know your legit post is going to be auto-killed and no-one is going to see it?

Good-faith posters should know that this is what is happening (assuming the auto-killing is intentional and not a bug) so they can go and try to build enough karma from their comments before posting a story.
