So... people imitate the posting patterns of legitimately afflicted by schizophrenia people? To defend themselves against capitalism? Wait, did I just fall for one such post?
However, I think that if you were to look for it, you'd find a lot of this stuff. Psychedelic culture, anarchist culture, etc are heavily wound up in this kind of dis-communication. It's culture jamming.
If you're confused by it, that's the point. Is it effective? Could it possibly accomplish anything?. Probably not, except that it makes the writers feel more free.
A great deal of 4chan "schizoposting" reads (to me) like normal shitposting mixed with with the "chaotic energy" of actual sufferers of schizophrenia, like Terry Davis. There's also an incel/"NPC" element, where people suffering from extreme isolation de-realize the others around them to rationalize their perceived harms. Mixed together, it's less "dis-communication" or culture jamming and more a confused complex of digital alienation. But maybe that's just alienation under capitalism, and brings us right back to culture jamming.
It's unwillful dis-communication. It is wretched and hateful.
One can spout forth unstructured writing that is abstract, confusing, but also beautiful, uplifting: something that draws you in and smothers you with warmth and living heat.
Alternately, there is dis-communication which proactively deconstructs, intelligently dissolving the stuff of thought into a primordial goo from which new life can spring.
This type of thing is none of that. It is a moaning for death.
And I'll have none of it.
