Majority if people call him KangKang. Zmjj is his brother’s in game name. He said that his brother has supported him through everything. That’s why he added the Zmjj. But mostly everyone calls him kangkang. And read Kang kang they don’t spell ZMJJ individually like you.
I think of the zmjj kind of like an org tag. Like how when you see NRG FNS you just think of FNS and not the whole name. So I can’t say I’ve had this problem.
