I belive this is a cry for help. You see, the autist is on some deep, unconscious level aware of his problem . He would like to stop, but in his mind it would mean admitting defeat. Therefore he is unable to confront it directly and simply quit.
Instead he hopes that if he shitposts hard enough, he will get banned, forcing him to quit, but allowing him to save face :>i never gave up willingly! I am still in the right, its the oppresive mods that set me free-i mean , that forced me to stop!
