"Actually that site has thin content. Rest of the other 4 sites have rich and awesome content where people are linking to heavily. They are health related, dental related, technology related and they have content that is forming source of reference for many. Believe me, if my sites were made for adsense, then i wouldn't get so many visitors who are actually linking back to my content heavily."
Like I say, I apologise if most of your content isn't like this one.
Why risk your your entire account by trying to drive CTR like crazy on this site? If you have good sites you should be happy and play by the rules all the time. I know you are not necessarily breaking the rules, but the page Adsense picked out and I am assuming there are more pages like that on that particular site, I am afraid you are doing nothing more than fooling the readers into clicking ads on those pages. You have good sites, so why risk your entire account?
Fix that site up as soon as possible.
