10 Reasons Why Your Adsense Account is Banned
This article is focused on newbie like me who just know Google Adsense. It is also for adsense players who want to take this as a revision in free time.
Actually this is from bro Inspiration that is active in WangCyber.com forum. The source is here. This article is translated from Malay Language. Thanks Bro Inspiration. Below is 10 reasons why your adsense is banned.
1. Invalid Click/Impression
This is caused by 2 reasons, we click our own ads or other people betray us. In first case, most newbie thinks that google will not know that he clicks his own ads to get earning. This is a FALSE beliefs. Even, there are people go to cybercafes only to click adsense ads in their website. When we click our own ads, google will monitor the click method earnt. Many factors will be analysed including the frequency happens, click location (IP and geolocation) and traffic source.
For second case, clicks are from other persons. To overcome this problem, we are advised to reaveal our sites that contain adsense ads to untrusted people. Beside that, activate “Only allow certain sites to show ads for my account” option. At least, we can control that Adsense ads.
2. Duplicate Content
This is our main problem. I know we are lazy to make our own articles, but there is a probability that your adsense account is banned, you have to make your own articles. If Google receive report that you duplicate content from original site, your adsense account will be banned.
In a situation like this, where you believe that a site containing AdSense code is illegally copying your site’s content, you can let us know by following the process described in our Help Center. It’s our policy to respond to notices of alleged infringement that comply with the Digital Millennium Copyright Act and other applicable intellectual property laws.

To overcome this problem, you have 2 choices. First is write your own articles or use tools to “spin” other articles. The main problem using automated tools is, you have to revise again the meaning of changed words so that the meaning of article is not changed. You can check your content in http://www.copyspace.com to know wether your content is duplicated content or not.
3. Changing your adsense code
You are advised not to change your adsense code.
We understand that it’s important for you to have control over the layout of your webpages, so we currently offer a number of display options for AdSense for search. In general, as specified in our program policies, we don’t permit modifications to the AdSense code. However, we do allow specific modifications that allow our AdSense for search code to comply with W3C HTML and XHTML standards.

4. Revealing adsense earning
Be careful when revealing your adsense eazrning for public view. Eventhough, our motive is to give motivation to other people. Do not forget to hide your CTR and ECPM.
5. Pornography
It is not allowed to publish adsense ads that contain
* Pornography, adult or mature content
* Violent content
* Content related to racial intolerance or advocacy against any individual, group or organisation
* Excessive profanity
* Hacking/cracking content
* Gambling or casino-related content
* Illicit drugs and drug paraphernalia content

6. Publish adsense ads in unsupported language sites
Eventhough someone publishes adsense ads in malay blog, but if we refer to Google Adsense TOS, it breaks the TOS of Google Adsense.
Please also be aware that placing the AdSense code on pages with content primarily in an unsupported language is not permitted by the AdSense program policies.

7. Made for Adsense site (MFA)
To maintain the importance of advertiser and site quality, google has made some criterias that is called “Google’s Landing Page Quality Guidelines”.
Publishers using online advertising must ensure that their pages comply with Google’s Landing Page Quality Guidelines.
8. Opening account adsense more than one
Like other persons, I also have more than one adsense account. For sharing, it still break Google TOS.
9. Privacy Policy
For every site that publish adsense ads, we should put privacy policy statement on that site. This is fundamental rule. Your failure to do that, can cause our adsense account is banned
AdSense publishers must have and abide by a privacy policy that discloses that third parties may be placing and reading cookies on your users’ browsers, or using web beacons to collect information as a result of ad serving on your webs.
10. Encouraging Clicks
Be careful during placing adsense ads because placing adsense ads near images is prohibited because it is categorized as encouraging clicks.
That is all for today. Share your experience that make your adsense account is banned.
Update:
There is one more reason why your adsense account is banned.
11. Your age is not 18 years old or above

I have heard of stories of ppl under 18 using and being banned

Oh btw, you should help promote nuffnang a little!
Many of these policies of Google Adsense do not apply to nuffnang.
We can reveal our nuffnang earnings to the public definitely, for one…
