I have, domain A, with domain B-F or so parked on top. Sooo they're identical, is it allowed by Adsense? They're all proxies (and making a shatload, so figured I'd make sure its ok) If its not, guess i'll just break it all up, have individual sites (just easier since it only uses the one directory)
It shouldn't be a problem, just make sure that you have a bit of content on this page, because adsense requires content on pages that display their ads.
