I just finished playing a PUG match and we ended up drafting Captin Crosser with our third pick (when we could have found a decent player still). He did not play the game at all--even from the very start. Had he played we might have won the game by winning on his side of the map.
I figure that either he just had no interest in playing or ICO dropped his connection without replacing him with an AI while still reporting that he was in the game. If he just minimized or went to sleep, then he deserves to be on a ban list.
