AIM SN Help

Hey, I have an AIM screen name that someone used to message me out of the blue... I have no idea who it is and they refuse to tell me, instead telling me to guess and playing games with me. Is there some way I can do a query on the name used to find out more information on who is behind it?

Just block them and move on with your life. Jesus.

"You've got 5 seconds to tell me who you are before I block you"

follow through, life moves on.
