Fanfiction Ratings System

Um... anyone else hear the rumour about a stink that the MPA is raising about people using their ratings for fanfic?
So several archives are changing to a new ratings system to avoid trouble.

FRC — Fan Rated Suitable For Children
FRT — Fan Rated Suitable For Teenagers
FRM — Fan Rated Suitable For Mature Persons
FRAO — Fan Rated Suitable For Adults Only

Thanks to Peja at WWoMB for pointing it out.
