He's found at http://www.furaffinity.net/user/96/ but he won't respond to any of my notes anymore. He's -almost- completed a commission I paid him for in advance, but the very last step is missing.
He does seem to be doing work for others in the meantime, though.
EDIT: When I sent a note with the text "Any chance you'll complete this commission or should I consider asking for a refund?", 9_6 finally, and quickly responded. He finished the commission the same day and offered a free image commission as an apology because of the delay.
