Google Adsense - 15 actions that should not be done

Hello dear visitor, as you all know at present I am posting regarding Google Adsense and I realized that it is better if I compile a list of what not to do. The following list include actions that would get your Google Adsense account banned:

1. Never click your own adsense ads or get them clicked for whatever reason. This is very important, do not ever tell your friends or family to click on them. Do not ever try to increase your income by using automated clicking tools. The Google Adsense team is very smart to detect fraudulent clicks. A remark I'd like to say is that if you have just opened an Adsense account and started clicking on your own ads, the Adsense team wouldn't close your account instantly. They would first let you "earn" $100 (minimum payout amount). Then when you'll be waiting for your check to arrive you'll recieve an email letting you know that our account was closed down. So please do not think that you're managing to fraud Google.
2. Never change the Adsense Code. It is against their TOS to change the Adsense code and it will lead to your account being banned.
3. Do not place more than 3 ad unit and 1 ad links or 2 adsense search boxes on any web page. Anyway, ads will not appear in those units even if you place more ad units. But this is the limit they set, so it is better to stick to it.
4. Do not run competitive contextual text ad or search services on the same site which offer Google Adsense competition in their field. Never try to create link structures resembling the adsense ads. Never use other competitive search tools on the same pages which have Adsense powered Google search. They do allow affiliate or limited-text links.
5. Do not disclose confidential information about your account like the CTR, CPM and income derived via individual ads. However what you can reveal is only the total money you are making.
6. Label headings as "sponsored links" or "advertisements" only. Other labels are not allowed.
7. Never launch a New Page for clicked ads by default. Adsense ads should always open on the same page. It's important, they do not want new windows to open from clicked ads.
8. Place ads only on Content Pages. If you insert ads in pages without any content you will get your account banned.
9. One Account suffices for multiple websites. If you have five sites you don't need five accounts. One account is all you need. It is against their TOS to have more than one account.
10. Do not mask ad elements. All ad components must be full visible. For example one can't have the text and backround both in red because the text wouldn't show. All the ad must be fully visible.
11. Do not send your ads by email. If you do so your account will be terminated.
12. Keep track of your content. Adsense isn't allowed on several content pages such as pages with MP3, Video, News Groups, and Image Results. Also hate-related, violent, illegal and adult content.
13. Do not alter the results after ad clicks or searches - Ensure you are not in any way altering the site which the user reaches to after clicking the ads. Do not frame , minimize, remove, redirect or otherwise inhibit the full and complete display of any Advertider Page or Search Results Page after the user clicks on any Ad or Search results.
14. Avoid excessive advertising and keyword stuffing - Although the definition of 'excessive' is a bit unknown and is subject to discretion, yet Google Adsense with correct placement, focused content and high traffic will get you much more income than other programs, so excessive advertising is not required. Keyword stuffing does target better focused ads, but overdoing it is not required.
15. Ensure your Language is Supported - If your web pages language is not supported, do not use the code on such pages.

Whenever in doubt, it is better to ask for adsense help from the qualified staff of Google Adsense. Should you want to ask me please do so by leaving a comment and I will reply.
