I think it's always sad to see censorship get a foothold. This affects all of us, even those who don't like underage stories. First it's underage, next it will be violence, and there are some who would like to see pornography go away altogether.
Best of luck to Those In Charge of the site. It's probably a wise decision to back away from the edge just a little; being shut down completely would really be awful. I hope that someday there is a place, real or virtual, where people can be free to express all of their fantasies without causing anyone harm.
