Well, it is undeniable WG did something he shouldn't, due to not knowing; he's regretting it now, and he promised not to do it ever again.
However, yes, I've considered that Zexorz didn't ask, which makes him slightly less at fault (I mean, if he asked, I'd most likely have delete the game), and that barman won the round (don't get me wrong: what happened shouldn't have happened and that's for sure, there again, but removing that round would penalize barman, who only was a victim in this cheating situation).
Now, this is the first time I see this happening in any of my cups, and WG promised not to do it ever again, as I explained him why it was bad; now though, if you want to be perfectly sure this won't happen in the future, I'm not against disallowing spectators. I'm really sorry that happened.
