All my sites got hit overnight. All the ones ranking on page 1 have not gone to page 2 and beyond for their keywords. These all use the same theme and have 1 Adsense block above the content. But each site has plenty of content that is unique and informative. I noticed many of the sites in the same niche as mine that have exact match domains and using Adsense got hit as well.
