Depends on why they banned it. If it is for something like invalid clicks, you will lose your account and not get paid. If you get a letter from adsense, it will tell you.
It is depend. If fraud click too many, they will ban your whole account. However, if some content issue, they might ban only one of your website and other website still can be used
Well... they'll specify what type of ban in their email. If they ban your whole account, it affect your all sites..
yea it depends if they just ban you one site and if other site is good site with good content they won't ban but if another site is also bad with frequent invalid clicks they may ban.
I had a similar issue with a free host I ran and used google ads on user sites. Lets say I own XYZ.COM and one of my users has 123.XYZ.COM and he uploaded pornography to his account. Google catches the pornographic content when the content is spidered by Adsense. Then Google sends "ME" the publisher and owner of XYZ.COM a warning stating that pornographic material was found on 123.XYZ.COM and that all ads for domain XYZ.COM have been disabled. So because of one idiot that violated the free hosting terms of service, My site was in violation of Adsense terms of service and all ads were disabled for my domain. I received two warnings from Google before I caught the problem. ( result of not checking email for a few days) If I had not caught it when I did, there would not have been a third warning. Instead it would have been an immediate ban of my adsense account. So I no longer use Adsense for free hosting client sites.
well, if pne site got banned then I would be pretty sure they would look at the rest of the sites on your account. So the question is do you have anything to hide? If you do, then I would suggest spreading your accounts out abit.
