My wild guess is that “Ismail Ax” is some moniker he used in an online game. Or some bizarre protagonist of his creative writing.
I’d say that’s a pretty good wild guess. The connection with Islam is very thin at best. Sometimes people over-think things or are too clever by half. Your guess is better than most.
Bah, he wrote it with the opposite hand, it's "Xa Liamsi"....sounds Korean to me...;)
