What are the safety precautions for adsense?

Hi. I am new to adsense. Please tell me what are the safety precautions for adsense? The safer sides you know please share it over here. Thanks in advance.

 

1) Don't click on your own ads. Google will catch and ban you for life.
2) Don't ask anyone online of offline to click on your ads. See rule #1.
3) Don't put images next to your ads that could be construed as related to the ads.
4) If there is a sudden surge in your ad impressions or clicks (if you get on page 1 of Digg for example) notify Google to expect the increase.

 

Don't change the scripts.

 

The above PLUS reading the Adsense Programme Policies:

Avoid clicks on your ads from your own country ....

 

thank you all. You have given a great help...........

 

And if you didn´t click in your own adsense ads ,still is possible to receive an email notification from Google Adsense team that you did it.
In this case,you must reply to them with any explain about your own logs and that you never did it.
