I used to use a site called bugmenot to get accounts like these but now as the passwords there have stopped working i have started to use throwaways.
Also my throw away password is 123456789 :P.
I was just thinking if my account is not publicly listed then I can just have a really complicated username and use a really simple password. (Complicated as in a SHA 2 or MD5 hash of your real name ). (Just thinking loud)
