I know this used to be illegal but when looking it up there was a few articles plus the google blogspot that says you can now use multiple publisher id's as long as you follow the rest of the TOS such as still only 3 ad units per page etc. I was wondering if someone could confirm this since I am about to do this on a website coming up and want to make sure it is correct.
Anyone who can help me with this it is much appreciated as I needing some confirmation on this to launch a website. Here is the article from google I am referring to http://adsense.blogspot.com/2008/07/sharing-your-ad-space.html. Thanks.
