Banned - You may not threaten this site or it's staff/users.
while they do provide a 'key' for the beta, it is linked to the account it was sent to and cannot be used on another account (so you would have to buy the entire bnet account)
also I believe it was stated in a press conference that they PLANNED on the beta in early sept... but blizzards idea of "planning" means "a month or two after this date"
