I have to add something to this.

Sorry - I just got into MBxing from a guildie in WoW.

Sometimes you simply can't create more accounts, in your name or otherwise. I started last night, used my "main" account as the referrer for four RAF invites to various email addresses, and successfully created accounts using my same real-life info as my main account. Well, all except the last one, which was denied by an error 203 on the account page. I emailed Bliz and they told me to call Billing and Support, which rang a few warning bells for some reason. It seems error 203 is when they flag your IP and details as creating too many accounts within a certain time period, so I am sat here waiting for my T7.5 Priest account and my RAF accounts to be banned, but at the same time I'm afriad to call Bliz and see what's going on so I can have a true 5-box.
This happened to me, I just called Billing, they helped me register the account that was complaining via the phone, trust me, they want your money.
