It's hard to believe anything DSP says about his finances at face value. If he was making more while not being in a network, then why be in a network? Sure, he gets a little bit of protection about copyright shit, but if it was that big of a difference then I fully believe he would rather take the money than the security. Obviously the copyright shit isn't that big of a deal if he's been going for a year without the network and he's gotten a handful of videos claimed, that he's then gotten remonetized/reclaimed after a day or two of challenging or whatever has to be done.
As for the CPM thing, if that's how socialblade figures it then it doesn't really change my point. The $4 CPM extreme for the high end is beyond what you're later saying is more than what you assume, and that would put him at their $35k mark, when you were saying that was the minimum in the post before that.
I'm not trying to be an asshole or start shit, but there's a lot of numbers that are just thrown around without rhyme or reason around here, and people just buy shit wholesale because there's like the tiniest bit of backing to them. What reason do you have to believe that he's making more than the minimum for his CPM? He has no audience, the audience he does have is dwindling, he has no pull, he has a history of talking shit about advertisers and endorsements, and a hundred other reasons that make him less attractive as a marketing tool. Where does this "we put him somewhere between $2 and $3 CPM" come from? Because it's in the middle and sounds nice? Three or four of his videos out of 40-50 of a playthrough will break 1k views. There's thousands of other gaymers on YT who pull those numbers. What on Earth makes you think he's getting more than the minimum?
