>a developmental disorder characterized by difficulties with social interaction and communication
!Akemi clearly can not socialize with others in a normal rational way, which is why he is obsessed with this site, because he can't actually talk to anyone in the real world. And even here, the only "people" (his other posts) he will reply to are people who already agree with what he's saying.
>restricted and repetitive behavior
!Akemi has been "bait" and "trolling" (failing to) in the exact same way for six years. Constantly repeating the same things over and over. (and then wondering why he always gets similar replies).
>Older children and adults with ASD perform worse on tests of face and emotion recognition
!Akemi thinks he's "triggering" anyone and everyone who says anything at all to him. He has bad face recognition as well, as he thinks everyone is "ack".
>Self-injury
!Akemi has literally destroyed his own life in his attempts to "troll" "ack".

https://en.wikipedia.org/wiki/Intellectual_disability
>Intellectual disability also known as mental retardation
>characterized by significantly impaired intellectual and adaptive functioning.
!Akemi has been doing the same thing for six years and he still thinking this is about "shipping" and refuses to acknowledge that the issue people have is with him making threads bad with his attempts to "troll".

https://en.wikipedia.org/wiki/Psychosis
>an abnormal condition of the mind that results in difficulties determining what is real and what is not.
!Akemi thinks "ack" is real when he has literally no proof supporting this idea.
>Other symptoms may include incoherent speech and behavior that is inappropriate for the situation
!Akemi makes up words, and constantly has inappropriate behavior for the situation. e.g. Constantly talking about "ack" in places where it doesn't belong and trying to attack people on a board that's meant for talking about anime.
>Delusions are strong beliefs against the reality or held despite contradictory evidence
!Akemi has been given waves of proof he's not "triggering" anyone and that "ack" is not real. He accepts none of it.
>Other delusions include delusions of reference (beliefs that a particular stimulus has a special meaning that is directed at the holder of belief)
!Akemi believe that the stimulus "someone is tell me off for shitposting means they are ack" when in reality telling off shitposters is the norm.
>grandiose delusions (delusions that a person has a special power or importance), thought broadcasting (the belief that one's thoughts are audible)
!Akemi believes he has magical powers to "trigger" people and that no matter what nothing can change this.
