I'm remaining neutral as I have not seen him in-game and I don't play CS:GO (maybe on MC? ScottNi will have to tell me his username) but I still want to put in my 2 cents real quick.
ScottNi has clearly made an effort to be kind and helpful, and I always appreciate that. 
ScottNi doesn't deserve to be shut down just because of PMs between him and a friend (for reasons which have already been explained by others).
However, if I did play CS:GO servers I would -1 this app. I just don't feel super comfortable having ScottNi as staff given the stories of explosive immaturity - stories which have their truth enforced by the PMs (based on how ScottNi behaves and nothing more).
I probably could've explained that better, but I hope you catch my drift.
