How one site is classified?

[disneyduniya]

Hello. I Recently noticed that you put a notice on my website that I need to buy some credits in order to keep my site running, since my site has been categorized as an adult site. Can you please explain how one site is classified, and how a kids based website turns into an adult website at all sudden?

My website:
www.disneyduniya.in

Your site is indeed not adult, so we will not block it. The problem is that we cannot show google adsense there (the adsense policy team complained about your site some time ago, so we removed the ads). We gave you credits that will keep your site running for a long time (probably several years). You can contact us if need more credits.
