re: How's the Facebook stock doing?

On Monday came an explosive claim that could give pause to brands trying to figure out if advertising works on Facebook. A Long Island start-up company said it was pulling its ads from the social network because it discovered that its ad clicks were far more likely to be coming from Web robots – or bots, as they are known — than human Facebook users. The company, called Limited Run, helps bands and record labels sell music and merchandise online. It bought advertisements for itself on Facebook this spring. It wanted to know who was clicking, so it built its own analytics tool. It discovered that only one in five clicks seemed to be from human beings. The rest, it said, came from bots, which, in essence, are bits of software performing automated tasks.
