Google has gone insane. I came to know this because I am regular reader of Amit (super affiliate) blog. Mainly it is affiliates who are getting targeted. Its not that if your website has great content then you may be spared. Google is banning Adwords account of even people with good content website. Even Adsense is also facing wrath of Google but Adwords accounts are getting banned per minute. So don't get surprised if your account get suddenly banned. Big G is mentally upset.
