Frauds are so typical on the all type of services. I was earning money 2 years ago on pay per install model , and there were many people who installed apps on own phones on differents ip. They thought : easy money , but on the end of month ban was comming faster than payout XD . It is normal , because people always want cheating... There's no way to change this because people are incorrigible.
