When someone leaves the game there is a fairly high chance they will take others with them by causing a server split. Additionally there have been reports of a lot of people not getting wins at the end of their game because everyone server splits right at the end of the game causing only one person to be assigned a win.
See http://forums.demigodthegame.com/357221 for another example.
I've seen this happen too, probably caused by splits and the the stats server giving the win to the first reporting client as opposed to arbitrating in the case of multiple reports. Que cheat tool soon that will cut you off from all peers in the game and cause you to report a win.
I'm surprised no one has made a drop hack already. I bet it would be real easy.
