I had several accounts with Google and they have all been banned. I tried to open another account and got stealthy about it, even did a remote desktop situation into a computer in another state in order to hide my IP address, didn't work.
I masked my identity in everyway possible and still got suspended before the account could be activated. I think one of two things happened. I used a different URL, different website, but I used the same content from a site that was associated with a google account that was banned. I believe google either traced back and found the duplicate content or they banned me based just on the website.
I make some of my money through adsense, but guess what, google doesn't want you to advertise a site that has adsense on it. I think any site that has adsense on it is getting banned or will get banned.
I searched google for a number of keywords in my niche and found that all sites that were being promoted were virtually ad free and were selling a verifiable product or service. I did not see one site with adsense on it.
What ticks me off is that google made the adsense product but doesn't want you to make money on it. Just so you know, my sites always contained up to date valid information that people could use and did use. I did not have a site that was gimicky or of poor quality, but alas it just doesn't matter.
