Well, I used my main (X) account to refer myself 4 times. I thought i'd share my experience. I was able to activate 3 accounts, then on the 4th, i encountered a problem. It kept giving me the 203 error when i hit create-account. I googled up and down, and... quick work around without calling or emailing blizzard. Different computer, different IP. You will be able to sign up instantly. I know i've read plenty about people getting the Error 203 so i thought i'd post what worked for me.

Thanks for the help guys.
