The key to success with Adsense is the placing of ads on pages that are receiving high traffic for high demand keywords. The higher the cost-per-click to the advertiser, the more you will receive per click from your site. Obviously, it does not pay to target low cost-per-click keywords and place them on pages that do not receive hits.
Considering the money to be made with Adsense, it is no wonder that they would want to get back into it. It is that same consideration why the Google Adsense click fraud is thought of and why many people are getting into it.
For this same reason, doing the wrong things in the Adsense and other forms of advertisements, whether intentionally or unintentionally, will result in a severe penalty, may get you banned and even have your account terminated. Nothing like a good action taken to keep wrongdoers from doing the same things over again.
