I was banned by Google. I had earned just $100 over a 6 month period for one of my sites and they banned me and never told me why. I asked to be reinstated recently and they refused. So, how do people claim to make thousands of dollars a day and never have any issues with Google. It is not possible. http://www.land.net
Not many people are making thousands of dollars a day compared to the overall number of Adsense users. How not to have issues? Well, it's rather simple. You need to actually read the TOS and Policies and keep up to date with them. Understand them, don't just tick the box that says "I read and agree to these" There are a lot of users out there who are not having ANY issues whatsoever with Adsense.
i think you can apply to google about reconsidering your ban and asking for reasons for banning i agree with adpubster that only some people are earning 1000 $ /day ... even it took 6 months to earn 100$ for me
