    I believe MSN made this change largely to counter search arbitragers, who had previously found safe haven in Ad Center. We’ve seen arbitrager activity on our MSN campaigns drop off substantially in the last few days.

    If that was the goal I think they failed, in a big way. Paid results from adCenter on msn/live are absolutely horrible at the moment.
