In late July Google's $90 Million Click Fraud Settlement was Approved and we now have reports via various forums that Google advertisers are now receiving the payouts.
WebmasterWorld has a two page thread with some comments;
Got my $6.45 wohhooo! headed to McDonalds for a Big Mac on google.
After spending $480,000 over 3 1/2 years I see a $280 credit in my account for Oct 20.
I've spent $188,000 this year alone, and my payout is only $30. This is a joke. I bet I've had more click fraud than that in on hour.
