its a temp ban, it can happen for many reasons,
reason 1: swiching accts / chars too quickly, spamming chat ect. ( lasts a few hours i believe)
reason 2: tried using invalid cd key to login to b.net, and a couple more sever offenses i believe ( lasts 48 hours to 2 weeks i believe )
you can easily get around it by swiching your ip address. If you can access your routers setup, i change my mac address and it swiches ip address everytime. very simple to get around.
