I had an adsense account, and then some guy comes to my website and keeps on clicking on my ads. Then Google bans my account. What can I do?
At this moment you have nothing to do with your ban account. You can make another site and following all instructions and obeying terms and conditions of Adsense apply for new Adsense account.
That's why I hate Google! They wouldn't even tell me why they banned my account and I never clicked my ads.
You should contact google authority then they can give you exactly what's the problem on your add that you are created on that site.
Google tends to ban accounts if they are suspicious. You could probably get banned. But then again, is your site competitive enough to get competitors to come and spam your ads? They know about this issues and they are adapted to it; Or no one would be left with accounts. Dearly, fdamours.
Once you are banned you are out and you will have to make new account. By clicking over and over under the same IP is a spam.
