“I joined the Yahoo Publisher Network, a beta program through which Yahoo provides text ads in much the same way that Google does. I started running the Yahoo text ads on many of my web sites.
A couple of days ago Yahoo sent me a notice stating they’d revised their Publisher Policy. Item ’11.l’ stated that I will not “display all or part of the Ad Unit to any user located outside the US”. In other words, I can’t allow users outside of the United States to view my pages if there is a Yahoo ad on the page!”
Further proof for my “Yahoo is evil” case.
