No. He was banned a long time ago. He went by Atlas and a bunch of other monikers I don't remember. Did you know all of the letters of "Atlas" is in Andreas' full name? Wow. Amazing.

If you do a Google Image search of Andreas, as I do every day, you'll notice he tends to wear a lot of blue. Atlas loved the color blue so much that he only used blue-colored lightbulbs in his room. https://bitcointalk.org/index.php?topic=68493

I wouldn't dare suggest to Andreas while face-to-face that he is/"was" Atlas, though. He'd probably punch me in the kidneys.... for blowing his cover, obviously.
