He claims it is alcohol that makes him talk that way but I, too, have seen him speak normally also alcohol doesn't actually mess up ppls spelling. I think he just likes spelling like that for his own personal reasons.
Not just alcohol; I think he mentioned being drunk a few times recently because he got even more incoherent and babbly for a short period of time, but he isn't constantly drunk afaik. Scott told me did drugs all throughout his teenage years, and told me he's had multiple incidents of head injuries within the past year and a half (a time period in which his spelling and grammar skills diminished quite a bit). Sometimes he can make a coherent sentence, but I'm inclined to think that it's more of a stroke of luck than him "forgetting" to put on a persona. But that's ofc just my opinion, and I'm not rly a professional in any of this to determine anything definitively.
