Under the name of the Senior Marketing Manager Koji Baba, they announced on their official blog,
It turns out that using blogs on the part of the promotional activities violates Google’s search guidelines, so we have ended the promotion. We would like to apologize to the people concerned and to our users, and are making an effort to make our communications more transparent in order to prevent the recurrence of such an incident.”
As you can see, it does not link to any other blogs or news items, such as our report or TechCrunch’s follow-up ( I’m guessing that TechCrunch Japan’s translated article is the direct cause for this apology.) So we cannot see “which activities” were violated nor how they will be fixed. How transparent!
