Join yahoo ads or an affiliate program, it is not always about adsense. And please use the search tool before starting such threads again. It is a common peon mistake.
If google ban you and you still want to join AdSense you may re-appply adsense and start AdSense from begining again. Make new site with different content from your old site and new email address then sign-up again to google. Indeed it's not always working for someone who has already banned by google but you may try and pray.
If you are talking future sense and it hasn't happened as yet then I'd advise to stop clicking on your own ads.
It can do, but the truth normally outs in the end. Setting up a new account using phoney details is not recommended.
Regarding contextual advetising you can try Yahoo Publisher Network (if you live in USA) or you can wait till MSN rolls out their contextual ad service. You could also create your own product or promote other products as an affiliate. There are many possibilities, but generally they will require a bigger investment that using adsense (building a list, using Adwords, etc).
if adsense account is banned ide suggest trying to work with them first. always try to find a solution. if your not wrong you have nothing to be ashamed of and plead your case. hopefully someone will listen. if not try CPA , YPN , etc
You don't necessarily have to break the rules, I know quite a few people that google have banned due to 'fraudulent clicks' and they swear they or anyone they know ever clicked on their own ads. These are people I trust and believe they didn't do it. There are alternatives to adsense that you can use, one in particular that can end up more profitable than adsense.
Then you should find Big Lawyer to sue google , try to get quotes from big law firms. also don't go with anyone charges less than 1 million dollars because google might find better lawyers
