Adding to the GP and P posts: I also play online FPS games, I am an admin with reasonable experience, and, most importantly, [b]I've had the chance to see autistic kids gameplay[/b].
And here's the thing: before I found out a player was autistic, their manner of play raised all kinds of warning flags for me. There were spurts of uncanny abilities, they wouldn't talk to anybody, they were focusing obsessively on a limited sets of actions (run this exact route, attack at these exact points), they displayed anti-social behavior (attacking their own team) for no apparent reason. My first reaction? What a cheater/asshole combo!
Has anybody considered how their repetitive/compulsive nature alone may cause autists to deviate from the player norm? Not to mention that about 1 in 10 autists show outstanding abilities ("idiot savant" kind) and about 9 in 10 exhibit enhanced sensory perceptions.
So I find it strange that most highly-moderated comments so far have completely ignored the fact the kid is autistic and how it may have affected his gameplay. My own experience tells me that unless Microsoft knows for sure he used an actual bug or exploit, I'd take that "cheater" verdict with a BIG grain of salt. I'm fairly confident that an autistic person can trip both automated and human cheater detection. They were designed for regular people.
