There are reports of people receiving fraud settlement compensation. A WebmasterWorld thread has following 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. "
