Its not a fake.
This class action has been going on for quite some time, and the settlement was made recently. The lawyers are taking 1/3rd of the settlement ($90 million). As I have gathered you estimate your loss to click fraud in your settlement agreement and then your percentage is worked out against everyone elses.... then you get your .00000000001% of the $60 million. In short if you agree to it you will get a few $ in advertising credits but I think you will probably only get around 2c in every $1 of click fraud you claim.... in other words next to nothing.
We spent around $800k on adwords the last couple of years, and I don't think we would see more than a few hundred dollars. I will be opting out of the settlement since I would have to forefit any claim in the future and I estimate our click fraud to be around 4-5%.
