Srats ranking pnms looks?

So I’ve heard that some of the sororities (assuming one or more of the top 4) have a criteria for looks and attractiveness for pnms going through recruitment during tours and other rounds to see whether are a good match for the sorority. Is that true? Because I’m ngl certain sororities definitely seem like they only recruit a certain type of girl for superficial reasons when I thought it was just all about genuine connections and vibes.
