From something he likes doing
That's the thing, I'm not sure that he does. His fans like to rattle off "You're just jelly of his success", but I actually pity him. I'd hate to turn a fun hobby into a full time job where I had to travel further and further to keep making and faking more and more extreme clickbait to chase those rare multi-million-view hits.
And the tragic thing is that he doesn't even seem to enjoy it, or not in any way that's healthy, as he has to constantly surround himself with grief and conflict. When he looks back on his career, I wonder what he'll have to feel proud about as a human being, beyond Bigger Number Better.
In terms of "yeahbut, where's the proof", there was a series of videos made 3 or 4 years ago detailing his shenanigans. He got them taken down with copyright strikes, and, as above, he does seem to re-edit the most egregious stuff after getting the initial views. He's
good at what he does, there's no denying that.
The incident that solidified my opinion was when he was deliberately shooting a couple of players in the face, explicitly to punish them, because "dead players don't talk". Well, they shouldn't talk about
game issues, but:
1) If he was 25 or 30m away from them, how could he hear what they were talking about?
2) In order to do this, he was camping their spawn.
That's typical of the stuff that I watched. The narcissist narrative is CHEETARS PUNASHED, but if you apply a bit of thought, he's often condemning himself more than the players that he's policing.
