How do you know that ? I have said before ,why for instance your sister can't share pc with you and have her adsense acount. It isnt your acount but her... Also he can have her own pc.. You can use combination of Adsense Adbrite and WidgetBuckets so you lost everything. Also for banned domain i sugest to use adbrite(+adbrite inline), Widgetbucks,and i think you can archive almost 10 cpm .5 adbrite and atleast 5 from WidgetBuks. Also you can get 25$ signup bonus from widgetbucks.,see link below !
