Can You Unravel My Mystery Username? Clues Inside!

[guess who]

Hey, I thought of a good brain teaser. I have another account on this forum. Try to find out what my other username is, there are hints in my profile that are NOT true, just clues. I expect some people to get it, so please, put the answer in white.
