I think maybe some congressmen/congresswomen, actors/actresses, etc etc do not list their GLO membership because it's not something they are "into" anymore.
Even though sorority/fraternity is a life-long committment, unfortunately, not everyone thinks of it that way. They see it as something they had fun with in college and that stage of their life is over.
I would definatley love to see more Greeks reveal their GLO membership! .. and better yet, I would love to see them all get involved with the GLO again
