Why i get Sale Reversals on every new item published on codecanyon :(

Whenever i publish any new item on codecanyon the first sale which i get is always a sale reversal, why does it happens?

Bro I have had 2 reversals for my product less than a week old. Now my script is on 2 different pirated sites and I know those who reversed took it there. Why can’t envato protect us ? It is really getting sad.
