Stark Raving Mad | KJ Stark | Substack
Looks like he had the rights to one of his short stories acquired by Sony (written under old pseudonym Nick Moorefox, referenced in the Substack account and article from Deadline linked below).
I've been waiting for an MSM source to confirm that KJ Stark / Nick Moorefox is the same person as Nicholas Kassotis, but it doesn't seem like they've picked up on it yet. It does seem like all of Stark's / Moorefox's various social media accounts have either been deactivated or have gone dormant.
These quotes form his substack are pretty telling:
I’m beginning some new things too. Life doesn’t look like it looked five years ago or two years ago or six months ago. I had a lot of endings: brutal painful things that dropped out of the sky and scattered my personal storylines. Now I’m figuring out how things look anew. I’m pitching ideas to people I admire. Writers I admire treat me like I belong at their table, which is so bizarre to me I can’t begin to explain. I spend all of my non-work time surrounded by happiness. My life is promising and beautiful in ways I couldn’t have imagined.
That’s hard too. I think about things too much, assume bad things will ruin it. I wonder if I’m cursed. When a bad things (even serious scary bad things) occur, as happened to me recently, and then causes a few probably foreseeable effects, I assume those effects will continue forever. A secret pessimism still lurks around the edges of my plans, whispering that destruction and woe are near.
