Hmm, as far as I can tell, we don’t have a stored record of your real name anywhere – just your username and email address. You may want to look into some anti-spyware solutions just in case, such as Microsoft Security Essentials, Malwarebytes, or Spybot.
If it happens again, try to snag a screenshot so we can investigate. It’s also possible you saw another player with a similar name. =)
