Thanks for your answer. Crazy (not just only troll) results like that happens indeed much more often.
But, can you tell me for sure that it has nothing to do with the fact of paying or not in the game ? I don't think so, because it's linked. And it's easily provable : someone who just buy prospected player (with tokens he bought with real money) is just unbeatable, no matter how good and better you are and no matter what you do.
