WebmasterWorld moderator, eWhisper, created a thread at WebmasterWorld on something he spotted recently with the Google AdWords quality score. He believes that AdWords has adjusted hows they handle proper names.

I'm seeing some odd results for names in AdWords. Many proper names have much lower QS in many accounts than a couple weeks ago. In fact, my own name, in my account, going to my website, is running a QS of 3 right now and the ad isn't even showing very often due to low QS. That's one of those situations where you know something is wrong as usually this is a 9-10 (and should be).
Are you advertising for names? If so, do let us know if Google smacked your quality score on those ads or not.
I am not sure why such ads would receive a lower quality score. I don't see the logic in such a decision or maybe it is something else.
