Getting an ROI through your PPC campaigns

I was hoping that it wouldn't happen to me, and that only you all would be affected, but this morning I had a few new keywords disabled.  The keyword in the picture was never a producing keyword, but one that has been in my ad group for a long time.  Today it went from a $.05 click to $10.00 click.

Obviously AdWords needs to do something about these, but what they will do, and when they will do it is the mystery.

Then again, didn't they test this at all before rolling it out?  Did they know the consequences that would occur before they actually rolled the new algo out of the lab?

It would be pretty crazy to assume that AdWords didn't know what was going to happen to advertisers before they changed this, don't you think?

Maybe the AdWords team knew exactly what would happen, but it works out better financially for them?  Anyone agree with the conspiracy?
