Earlier this year, Google revealed that we sent out over 700,000 messages to site owners in January and February 2012 via our free webmaster console athttp://google.com/webmasters . I wanted to clarify a misconception about those messages. A lot of people assumed that most or all of the 700K messages were related to "unnatural link warnings" that some site owners received.
The reason for sending the 700,000 messages via Webmaster Tools was actually because we started sending out warnings about blackhat techniques. The vast, vast majority of manual actions we take are on pages that are engaging in egregious blackhat SEO techniques, such as automatically created gibberish or cloaking.
In fact, of the messages that we sent out to site owners, only around 3% were for unnatural or artificial links. So just to be clear, of the 700,000 messages we sent out in January and February, well above 600,000 were for obvious blackhat spam, and under 25,000 of the messages were for unnatural links. #smx #seo

I believe the site could of triggered something NOT due to links...
