You did nothing wrong, you won the match. End the discussion there, losers don't get to pass judgement, they lost.
Im currently levelling up my Kenshi online. Hell, i KNOW i'm a spammer, i'm one of the biggest damn spammers going. Oh wait no, there goes another rage quitter, i wish they would stop spamming the quit button so much so i can get some match up experience for more than half a round!
