Dream11 Fantasy — Unfair playing in dream11 contests

I am playing dream11 since last 2 years and observed that not a real person won any single mega contest. I want to know one real person who win the mega contest and earned crore. I searched the winner name n msg them but never get any replies.
Also i observe that, when a player who is not in my team(selected by 10-20%) score a single run(1 ponit) my rank decrease by 2-3 thousands, bu when a players who I have selected in my teams, even he take a wicket(25 or 33 points) my rank increase by less than thousands.
Something very unusual here. They are using bots, and modified team in backend and looting the ordinary people.
