Is This Click-Fraud?

I’ve been seeing lots (and lots) of traffic at work from two particular domains


which both sound like click-fraud houses to me.

I have looked at their sites and both offer to “pay you to read email,” which, again, sounds like nothing more than click-fraud. My guess is that they show you an email with an AdSense ad, or Y!’s ads, or whatever, and then you click on it. They get the revenue from the click and share it with the person doing the clicking. But the advertiser is paying for ad impressions/clicks to people who have no desire to buy the product or service, and are only clicking on the ads because they are being paid to do so. How can this not be fraud?

Am I wrong on this? If I am, then my apologies to the two websites. But I don’t think I’m wrong.
