Here's a way to draw attention to click fraud. Sue Google, Yahoo, TW, Ask Jeeves - all at the same time. Covered in the Wall St. Journal. Not bad.

The plaintiffs, led by Lane's Gifts & Collectibles LLC, a Texarkana, Ark., retailer, allege that the Internet companies knowingly overcharged for advertisements they sold and conspired with each other to continue doing so. The plaintiffs are seeking to have their suit, which hasn't received widespread attention, certified as a class action.

The search engines have antifraud systems and sometimes issue refunds for bogus clicks. But they decline to comment in detail on the scope of the problem, exactly how they are fighting it, and any specific instances of click fraud, in part because they don't want to tip off fraudsters. That has fed some advertisers' fears that the problem is bigger than the search companies acknowledge. Estimates of click fraud run as high as 20% of all clicks on search ads.

You know what they say: "Sue them all, and let god sort it out..."
