honestly there is zero evidence linking him to gh15. You might as well guess it is Phil Heath. No reason to believe one over the other than more. No idea how this stupid rumor made the rounds to begin with
actually whoever it is, and its most likely nasser, made a deliberate attempt during his early years to make the account appear to be dj. if you go through his posts there are very many things linking the two. milos sarcev even thought it ws dj, to the point that the confronted dj personally about it. dj denied. from references to relying heavily on crystal light, which dj talks about in his videos, to his german background, to a thread after the 2007 ny pro in which gh15 made a comment implying he was dj when someone said dj was robbed (having got 2nd to wolf), to a picture thread dedicated to james in which gh15 uust posted "nice pictures

" at a time when gh15 wasnt posting much in threads except for when related to his main subject or in a "pm answered" thread. .. plenty of reason to think its dj. just that nasser basically admitted its him already on several occasions.
