On window live some people in the world are faking there name age and birthday but the computer can't see that there wrong so i'll say if you fake it you pay for it. I am also talking about facrbook which is a bad site do you know what happened to this kid he got killed do u know why because he had some friends(boys of course)and they done something horrible they killed him so thats why some people 18 and under should never go on this site.
