In a WebmasterWorld thread, a member accused MSN for making his site suffer because he had placed Google AdSense on the pages. MSN threw a shocker by responding to the mail. MSNdude (official MSN representative), replied to the thread-
That's certainly not by design. I suspect something else is wrong with your site to cause this. However, we'd like to check this one out — just in case — because if it really is our bug, it's very serious and we'd want to fix it immediately.
After Google's eyes and ears Matt Cutts grabbed the limelights of the search engine world and showed Google as more sensitive to the webmasters, this is MSN's turn.
