Well in his profile hes claiming hes 12 yrs old,its possible english is not his first language.
He could be dyslexic and may REALLY be retarded.
I very much hate to say it but if any of the above was true and he was banned,his parents have what in legal terms is statutory rights,which are outside rules of the forum,and they can take legal action of the highest magnitude allowed.
It would be discrimination,people THINK you cant break the law online,this is a false belief,mainly due to psychological awareness of talking on a computer rather than talking or acting in real life situations.
I cant imagine a case ever really gets off the ground,but its a risk banning people like this,albeit an extremely small one.
Put simply it aint worth it.
