I would like to know if my sites get banned from google and the adsense applied from different users on that sites also get banned.
What you are having an ad revenue forum or something like that, how can your users get banned until and unless they provide their pub id to you and you display ads from that pub id, then when your site gets banned, of course all those pub id's too get banned, if that was your question
I want to know if my site gets banned then the adsense account also gets banned applied on that site.
