Yeah, if you're just bad, then having Krimbo give his opinion on you isn't going to help.
More, do you think he's going to do that?
No, he's a sensible (ish) streamer. He's got some nouse. He's going to pick unlucky streamers, those who have potential, and use this opportunity to boost them.
What bonus does it give him to watch some random, who nobody knows and dislikes, and say "Yeah, this is trash, you should give up"?
It makes him look mean. Not even in a kayfabe way, of being a tough boss. It just makes him look like a dick.
Instead, he'll pick people with one or two flaws, and tell them how to improve. He'll also pick one or two people who are legitimately good but have a small following, and boost the shit out of them. Maybe bring them into the Hang-gang, or whatever it's called.
Or maybe I'm an overly pessimistic guy. Maybe he's going to provide useful hints and tips to everyone who applies, and do it out of the goodness of his own heart, and there'll be no difference between how he treats those who might make it, and those who are going to crash and burn in a week.
