This is the email from Google which every Adsense publisher worries about. We all have heard horror stories of Adsense accounts getting banned due to no apparent reason. Google is also well known for not providing any response to emails sent in this regard. And really there are to many ways you can get banned, without any fault of yours. What do you do if some of your competitor repeatedly clicks ads on your site with the sole purpose of getting you banned?
So there are some steps you must take not to get into any problem
1. Donot, repeat donot click on your ads ever. Ok I will say it again. Donot click on your ads ever. Google has pretty strong views against it and will disable your account right away if it detects such fraudalent clicks.
2. Donot place ads on sites which in any way hurts Google sensibilities. These include, but are not limited to, pornography, gambling, drugs and similar entities. Donot even put ads on similar sites. Horror stories include getting banned due to putting adsense on "Free Poker" sites. Google probably classifies it as gambling.
3. Never ask your users to click on the links. It is against Google's policy. Recently google won $75,000 against a Texas based companyAuctions Expert.
4. Donot put too many ads on your website. Though too many is subjective, Google specifically has a clause against too many ads. But you will have to go really overboard to get banned due to this reason alone.
5. Be proactive. If you notice many clicks, and suspect someone may be out to get you banned, contact Google before they contact you. If they discover it first, its will not be very plesant.
