He is not mattvision. That isn't to say that he's Not_Mattvision, because that's me, another one of the many accounts on Phuks that is not mattvision. But he, like most of us, isn't mattvision.
Additionally, @HateCumbuckets isn't mattvision either, and glixymon isn't mattvision but mattvision was a glixymon alt.
@unruly is a Jessica Yaniv alt but you already know that.
We are all mattvision
