If you are banned from Adsense....
Besides Yahoo PN, you can use CPM campaigns to earn some income.
This is good if your page views are high, at least 5k daily.
CPM pays around $0.3 to $0.7 depending on your website and the
ad company. So if you put 5 different banners or popouts (pay higher),
you are looking at $10+ daily, which is not bad.
