Adsense revenue sharing for multiple authors

Hi,

I have blog geekspage.org. I want to make it adsense revenue sharing blog. But I have a problem here, I have authors who write articles on my blog, some of them have adsense account and some dont. For those who are not having adsense account I am displaying ads from my adsense account using shortcodes. Using this method I can also display ads for authors who are having adsense account using shortcodes. Until now fine, but the real problem is i want to display ads for my post without interfering with other authors. I have already written 217 post, using shortcode is not possible. Here i can use adsense revenue sharing plugin to display my ads and ads of authors who have adsense accounts but what about authors who dont have adsense account. Here my idea is I want to disable the adsense revenue sharing ads for this particular author who dont have adsense account so that i can use shortcodes for displaying ads. Any one please help me. I dont have any knowledge of PHP.
