The subject says it all- MSN Robot very often visits the URL that I put into Adwords. He comes without any referer, with his User Agent and the IPs like 126.96.36.199. I don't have a clue how does that MSN know about my ads as they even still didn't start showing up? And wonder what does he do there at all, I don't see my landing page indexed in Bing so it seems like it's not indexing. Even GoogleBot doesn't visit so often.
