How has this affected your earnings when you: 1. Compare June with the past few months? 2. Compare June 2007 with June 2006 and June 2005?
Overall the impressions and CTR weren't affected, but I am seeing a noticeably higher eCPM as of May 19. So I have a theory on this... Not only did Google boot some of the obvious MFAs, they also raised the minimum bid on quite a few terms. I think that's what caused the increased eCPM, which translates to higher earnings for publishers (and more profit for Google).
