text messaged me said they got my number from facebook even though my number is not on facebook. said they were jamal jacksons, fifty cents friend, and were terribly sorry

the person with this number keeps texting me, and i have no clue who he is.  he says "ima h.s. Student graduated, black american, tall, blak hair, n 18 yr old mail."    i have no clue who this guy is, and he keeps saying he has to "asks me some ?'s"   even though im not responding.  its freaking me out.

This person texted me saying his name is Jack Hudson. He texted me asking what school I go to and he said he got my number from facebook too. He said he needs to ask me some questions because he doesn't know me well.

he texted me and said his name was jamel jones, told me that he didn't know me, and said that he got my number off of facebook. he's also texted at least six other girls from my school, but sometimes uses the name justin mullins. he claims to be sixteen he's asked girls for pictures and apparently sent a picture of himself to a friend of mine

texted me saying his name was jamel and said first "hi" then "can i ask you some questions?"  then "wat skool do you go to?" its really weird. does anyone know who this is?
