Who called from 7083776639

I received a text message from this number today saying 'Hey'.  I have no idea who this is and text back asking them if I knew them. Probably should have ignored it.

Also recieved a text message Jan. 17 2013, @ 6:49....Hii :P from this #....... have no idea who this is, they wouldnt answear back text.......

I just got a random text message on Jan 18, 2013 @ 3:24pm
I located and traced the message was sent from IL, well for the area code for the number it does.
This what I got:

17083776639: Hi :)
Me: Hi, who is this?
17083776639: How about we chat on Ya-H00 msngr Screen-name is mariahgirl6
Me: Who the heck are you for the 2nd time. I don't know you. Can you read are you blind? No Thanks.
17083776639: Cool :)
Me: Thanks for continuing to chat with me, I traced you! Trolololol along the way to jail! :)

After that text, NO response back what-so-ever! Who ever it is must be scared to get caught and thrown in jail. Oh well!

Someone texted me from (708) 377-6639.  I replied WHO IS THIS?  Got "Let's talk.  My Y IM screen name is berenicesmile.

Ignored from there on.  SPAM.

Same here.
