I have another good ad company. It is Oxado. Oxado has ggo types of ads because they rotate every two seconds giving the user/member who is viewing your site more chances to find an ad that interests him. Also it has a really good administration area which is securer than some ad publishing companys.
I would recommend Oxado if you have been banned from adsense. The url is http://www.oxado.com
. Its worth giving them a try.
