You and Google might be the only one who knows why you got banned. What sort of content does your website contain? (Adult, Gamble, etc maybe?) You should read the Adsense policies and you might find something.
dont feel much, There is no reason to banned an account. But the reason is only one thing. Invalid clicks. Its not ur mistake , but badluck
Sorry to hear this... But Google does this sometimes, and this is the answer they give to all people no matter what they did, or didnt do. So only Google know why, but the thing is they closed ur account and it will stay closed. For you peace of mind, in most cases its about invalid clicks ( you click your own ads, or someone that know ur site, and maybe wanted to help you make extra cash clicked you ads, or, you places ur ads in the wrong section or 2 many of them, there is strict rules wt where and ad can be placed and how many times, and places, if u placed it wrong, then, that is why) Hope this helps Regards
Google Adsense can be really suborn at times. The only hope you have now is to get a new IP, and create a new account. I feel for you, as my Adsense account was banned before aswell, but all you can do is create a new account and hope they dont find out.
Nobody is wrong, just because your site is providing low quality click to the adsense and they ban you to protect the advertiser. It sames happen as you are providing low quality service/product to your client and your client stop buying service/product from you
