You know what Sunbat... Let it go man. It isn't healthy to be that obsessed.
Honestly, if Ak AK works for a game company then his opinion on quite a few topics in these forums should carry some weight. Just as, I am a professional photographer, so if we were talking photography, my views should carry extra weight. And yes, every thread that I post in as a professional photographer, I would probably feel obligated to establish my bonafides.
Are you saying that he is lying? Why should he have to prove who he is to you or anyone else. If he is lying, I would think that it would be pretty obvious by the context of his posts. I've never seen any post of his that makes me doubt that he is what he says he is... Besides, why would he want to "prove it". If he is what he says he is, he knows it and won't "prove it" because it is more fun to watch you guys gnash your teeth over it. If he is lying, then he is definitely going to perpetuate what may be one of the top ten trolls ever. There really is nothing to gain by "proving it", unless he really cares what you think. Which I suspect he does not.
Please consider, I have no reason to love Ak Ak. Heck I don't know him at all. He did pick me earlier tonight while I was having a nice fight with a Spit 8 in my Ki84, was going to post the film in that Training thread, but oh well. But I don't hold that against him, heck I pick people all the time in the MA... Getting picked is a failure of MY situational awareness, nothing more.
But putting in the effort to post all of those quotes is borderline crazy town. You might want to take a hard look at why it matters so much to you...
