I gave access to the guy (I called the google helpline) a couple of weeks ago so he could fix a problem in my (new) account & forgot to deny access after he was done. Two weeks later, yesterday he accesses my account with no prior permission other than that he had and changes my manual bidding to auto and lowers my max CPC by 80%!!!! Good thing I caught it around mid day today, my add was at the bottom of the page! Checked my account and scratched my head :dunno: long and hard as to how that had happened. Changed it back, got back up to my desired position and started hunting for the culprit. I took his account off mine and I have his email address but I don't know what to do as I don't want to awaken the :google2: giant. Have you guys had any experience like this and what did you do?
