I am not sure that different Adsense account would be used on one domain name or one page or not. As we allow adsense to everyone whoever the users are posting articles with Adsense code. But I am not sure if it would be banned by the Adsense manager because they want to assign only one Adsense account on every domain. Tell me about it, would it be used or, would it be beneficial or not? I allowed Adsense because in promotion I would soon get good results as users would be beneficial for posting articles on my our directory.
I suppose it can be allowed, seeing as hubpages (and probably some others) are doing it. This very forum at one time had it.
