Doubt it. If MSMG is anything like Sylc was, people wouldn't. It's all in his personality, obsessions, and maturity. All he ever talks about is himself and Doors, which I suppose might fit in with MSMG if it weren't for the other factors.
There's a difference between Geevee-Immature and MSMG-Immature, and those two would not mix well. MSMG-Immature is all about occasional mature jokes, mostly from Andrew, and not being very tolerant towards children due to intrusion in their domain, if you will, and Geevee-Immature is all about forcefully involving himself something that has nothing to do with him (Example:the post in the Fralex stream), talking about Doors or his OCs whenever possible, and he has a negative reaction towards mature jokes, likely leading him to say something about it, which the average MSMG user wouldn't respond well to. Then a big argument would break out, like what happened with Iris, Geevee(or Dusk as you'd know him) would say something about it in the ES, some MSMG users would probably end up following him here, and then we'd have a total disaster of a stream due to some sticking around just to continue harassing Geevee but ending up harassing more Geevee-type users here, which we have a lot of.
