Adsense donts for those who are serious about earning online

Are there any restrictions while using 'Google AdSense' as an earning porgram? There are certain rules and regulation while enabling 'Adsense' as an earning way to your site.
These are some donts to keep in mind when you use this amazing earning program to earn online.

• Don't click on your own ads or get your friends to help you. 
• Don't draw unnecessary attention to your ads. Even posting text that says "please click on these ads" is against the policy.
• Don't share how much you've earned.  It is against the terms and conditions and account can be suspended.
• Don't edit the AdSense code.  Leave it the way it is if you want to get paid.
• Don't use scraped content. It’s a violation of Google adsense policies.
• Don’t create multiple accounts. Publishers are not permitted to maintain multiple AdSense accounts under the same payee name, and having the ad code of different accounts on the same website will not affect your CPC in any way.
• Don't try to implement your AdSense code in a place where people won't be able to see it. There are many people who try to offer incentive to visitors so that they click on the AdSense ads.
• Never place your AdSense ads on empty pages.
• Do not display more than 3 google ads per page! 
•  Do not put google adsense ads on restricted websites or web pages or not to put your google ads on somebody else's website. (Unless they are trusted websites) 
• Don’t try to manipulate the standard behavior, targeting, or delivery of ads in any way that is not explicitly permitted by Google. 

In case you have any doubt, read the AdSense program policies.
