Visit a Site HITs
It takes you here, where it wants you to click on one of two redirection URLs. Which are redirected by an Advertising agency, whose affiliate program's TOS states
".12. You agree not to artificially inflate the number of clicks, impressions or other activity, nor to permit others to do so"Using mTurk to inflate the numbers is clearly a violation. Now all of the questions in the HIT simply allow the scammer to figure out what pays the most, and whether you actually clicked on the ad or not (the IP request).
Now on mTurk's side, it doesn't appear to be a violation of the TOS. But obviously advertisers don't pay people to pay others to pointlessly click on their ads, they pay you when people who are interested in the product click on their ad, not when you pay people to click on them.
So here's basically what Phillip Tattum has setup, a Turker clicks on ads on his website, the advertising agency pays him so much for every time an ad is clicked, he then pays the Turker 5 cents of this. So the Turker profits, Phillip profits, and the company that paid for advertising gets scammed. Not Good. I've forwarded this to Web Gains so they can take a look.
