He's not as childish as PewDiePie, but childish nevertheless.
His Draw My Life video comments makes me want to punch the computer screen. I mean, I don't doubt his story, but the comments that are all "Oh, you're just an amazing person, Mark" and "I'm in tears right now" just piss me off. You don't even know the guy in person, and there's people with shittier lives than him, and not a single tear is shed for them.
