Google Adsense Bans hell lots of Publishers

Google Adsense have banned many Adsense Accounts of many publishers for a common reason stated as the publishers accounts are of risk for the advertisers.
Adsense have not said an appropriate answer to the publishers. I have seen many publishers exhibiting their anger in the forums for not telling appropriate reason for the publisher. But its the publishers responsibility to take care of the account which could have created a risk for the advertiser. Google Adsense cannot be questioned in any sense for not answering the questions asked by the publishers.
Google Adsense is very clear in their stand that they work well and for the goodness of the advertiser rather than a publisher.
