A category named "Explicit" appeared for a short time at iTunes Connect, the developer´s portal, where applications are submitted for official approval by Apple before they can be published at the App Store. Recombu took a snapshot showing the new category as evidence, although the website later reported the category had been removed. Probably the guys at Apple still do not feel like announcing the news and tried to cover their tracks, even if with a slight delay. Still, it seems there is hope that the company will eventually activate the category dedicated to software with explicit content and perhaps, deploy some kind of parental control system along with it in order to prevent kids from accessing the programs, which looks like a much better option than imposing total censorship across the board.
