I think it's supposed to be a joke! The kid's command of language way surpasses the equivalent of his spelling, and it's almost all typos rather than spelling errors so it's not even like he's dyslexic; I think he's trying to parody skript kiddies by acting like one, but it's not because he can't physically type correctly - check it out, those are HARD typos to make, he's either got a program to do it or he's spent a lot of time carefully correcting to get consistent typos. Bless him for trying! I found it quite funny actually...
