You are right. Adsense is also not effective on this site, but Adsense was the only way to monetize the site. Google deactivated Adsense without any warning, so I had no time to remove Adsense on pages with little content.
You probably shouldn't have had them on pages with little content in the first place. You did break one of their policies, but if it's not effective anyways, you haven't really lost anything.
