  Google and Facebook being two of the most valuable companies along with hundreds of billions of dollars and petabytes per hour. What kind of evidence are you looking for exactly?

      Uber was a victim of fraud, not a failure of advertising. They should've known better and used more checks to catch it quickly but they already run plenty of targeted campaigns precisely because they work well.
