Alright, keep your pants on! I don't have W:A installed here, so I can't check the games myself here, but I'll get on it when I get home.
I don't know who exactly proceeded the groups, but you can't expect mods to check up on every game whether they've been played or not, beer. All they saw was crash having won 2 games and played them all. Of course that would lead them to advance crash.
The chat in his game against inza suggests a wrong replay/manipulation of results. His game against Doritos suggests he was playing WxW, which definitely isn't the scheme of this cup. But I don't want to make any kind of decision without seeing the games personally.
