$90 Million set aside for Click Fraud

Google are about to settle a click fraud case, and Google say at their blog:

Google currently allows advertisers to apply for reimbursement for clicks they believe are invalid. They can do this for clicks that happen during the 60 days prior to notifying Google. Under the agreement with the plaintiffs, we are going to open up that window for all advertisers, regardless of when the questionable clicks occurred. For all eligible invalid clicks, we will offer credits which can be used to purchase new advertising with Google. We do not know how many will apply and receive credits, but under the agreement, the total amount of credits, plus attorneys fees, will not exceed $90 million.
