2 brand new accounts 1/1 perma banned

[dragonbuddy]

So blizz perma banned 2 brand new accounts for exploit of economy. One was on an old bnet account that had bans and 1 on a brand new one, new fake name etc. . Neither has done a thing to do with any exploit economy, nil auctions nil gold sale or transfer. They both had the paypal upgrade from trial for 10 usd processed then banned same day. My IP address was released and renewed before creating these accounts. So I guess it has to be payment method flagged (paypal account) ............ thoughts guys?
Anways I am doing a chargeback on these 2 since they had done nothing bad at all.
