But there are stories with 5 or more rating and 5 or more posts and more than 2 weeks old.

Current examples include "Exceptions", "The Cardinal Curses", "Harry Potter and the God of Lies", "The Awakening", "Nullifier", "Oblivious", "Half of Dueling Range", "The Preservation of Memory", "Hatal Fart Attack", "Albus Dumbledore and the Everlasting Flame".

My guess is that real criteria are "Less than 5 ratings, less than 6 posts, or less than 2 weeks old."
