1. Ignore Adsense Program Policies & TOS
2. Click on your own ads, specially those you are “genuinely interested” in. Ask people to click on your ads: your friends, your family members, your relatives, your visitors, or even your dogs or your cats. Use proxies to avoid detection.
3. Participate in some form of click-ring. Click-rings are groups of people who gather with consensus to click each others’ ads. Most commonly used methods are Yahoo Groups, instant messenger, mail list, web forum, or specially written software.
4. Buy, write, or use click-bot software. Click-bot software will go around your site and click on your ads. Most of the times, these click-bots are using proxies to avoid detection.
5. Pay the Indian-clickers. These are the people whose main jobs are clicking on PPC advertisements and paid by the malicious publishers. Most of them are from developing countries like India or China.
6. “Invest” with websites that promises to deliver “adsense clicks” for your site. Whatever methods they are using, most likely it falls under one of the aboves.
7. Extra words to make your visitors to notice your ads. Write “Click here” or “Please support us” or “Visit our sponsors”. Anything other than Google-approved “sponsored links” or “advertisements”.
8. Put in as many ads as possible in every page. Put more than three units of the normal ads block, more than one unit of ads links, or more than one referral buttons for each adsense, adwords, and firefox; all in one page.
9. Use spyware to get traffics to your site. Spyware, adware, malware, or whatever it is called can force computer users to open your website everytime they start the computer. Or even better, use some kind of specially written software, toolbar, etc to display or click on your ads.
10. Use pop-ups on your website. Everytime your user open a page, pop-up another one, ideally with the smiley or the IQ Test advertisements.
11. Get as much un-targetted traffic as possible, for instance using the auto-surfing programmes to rotate the members around your site and other sites.
12. Put the adsense code in non-content pages: registration forms, term and condition, login page.
13. Have a competitor contextual ad on same page with adsense ads, for example Yahoo Publisher Network. Please note though that non-contextual ads, e.g. affiliate links or keyword-based ads are acceptable by google and won’t get you banned.
14. Get more than one adsense account. Maybe one for your dog-site, one for your cat-site, one for the v1agra pills, one for mp3 download, etc.
15. Put your adsense code in email the email, usenet, RSS, etc.
16. Tell everyone what is your CTR, your page impressions, etc. Telling people about your total earning, unfortunately, is allowed.
17. Put Google logo where you shouldn’t, and don’t put the logo where you should. In other word, ignore Google trademark.
18. Modify Adsense code as you see fit. Modify the layout, color, URL, will be well. Just anything other than copy-and-paste the code from Google.
19. And, this is important: if and when Google Adsense Team sends you email, ignore it.
20. Put adsense codes in the banned contents

What is constitutes invalid clicks? This is what google says:

Invalid clicks are clicks generated through prohibited methods. These prohibited methods include but are not limited to: repeated manual clicks, or the use of robots, automated clicking tools, or other deceptive software.

Please note that clicking on your own ads for any reason is prohibited, to avoid potential inflation of advertiser costs. All clicks must be generated as the result of a user clicking on the ads. We therefore require that Web pages do not include incentives of any kind for users to click on ads. This includes encouraging users to click on the ads or to visit the advertisers’ sites as well as labeling the ads with text other than “sponsored links” or “advertisements.”

Update (15 April 2006) : Someone suggested that having the word AdSense in domain name might get you banned as well. I contacted AdSense Team to clarify that. Domain name with “AdSense” will not get you banned, but the may just decide not to display ads for that specific domain. I have removed the AdSense blocks here out of good will, but still have it on my other websites.
