Oba Mina of Team 4 has been suspended do to things she posted on her blog. Even though most things had a reason, it was the totality of inappropriate behavior that caused the suspension. In other words, management felt that Oba Mina, as an Idol representing AKB48, should have watched and been more mindful of her image.
