I got banned even if i reconnected as soon as possible and won the game

[marcoamogus]

I got banned because I disconnected during a game but I've reconnected as soon as possible since my pc crashed and and a deadlock file got corrupted, I managed to reconnect to the game and we won while it was still a 6v6. Even though we won the game my rank has dropped(I was archon 5 now im archon 4 and I won in an avarage oracle 3 game.
