Well, MMO-Champion is for more than laughing at people and their doings, or bitching about something. People should also be there for you, currently I am in a bid war on an invitation, it's been going on since it was put up. *smiles*
But just know, if I was you, I would contact Blizzard and have them restore the invitation and put it in your bag. They are able to do this even if your account is frozen, then if you ever decide to return then you don't have to offer money to try it since you have it. But as the tooltips says sometimes, take things in moderation, even World of Warcraft. And it's christmas, spend the time with friends and family, hunt for those annoying gifts and beat someone up in the queue to the counter (Though I don't recommend it, but sometimes in christmas, self defence is needed even more).
