Adsense must fix:

• Visiting your website and clicking on advertisements. Getting others to do it for you or paying them to do it for you.This isn't a level playing field. You wouldn't want to pay for clicks from users who aren't really interested in your product or service if you were the advertising. As a result, you must not click on advertising on your own website or attempt to 'artificially inflate the impressions or clicks the ads receive, either manually or by automatic means.'
•  Bot or automated traffic-Although this may seem obvious, it is a typical Google Adsense infringement. So, as a reminder, don't utilise bots or other deceptive software to automatically produce impressions and/or clicks.Be cautious with paid traffic; it's not illegal, but you're responsible for monitoring the sources of traffic, and if you use artificial traffic to drive traffic to your advertisements, you'll be the one to blame and in violation of the laws.
• Ads that are misleading-This is a big breach of Google Adsense standards, whether it's a modification in the ad's design or its placement in a way that could lead to more unintended clicks.
• Manipulation of ad delivery-Putting a slew of keywords on your site is a quick and dirty method employed by a number of publications to get more traffic or quickly generate content.
• Including advertisements in software applications-This is yet another Google no-no. Publishers are prohibited from placing advertisements in applications such as toolbars, desktop apps, browser extensions, and so on. If you wish to deliver advertising in your mobile apps, you can only do it with the AdMob SDK.
• Serving ads next to illegal or copyright-infringing content Context is everything, and whether an ad appears next to a reputable news item or a shady manual on how to produce counterfeit documents makes a tremendous impact for advertisers.
