How can i have old myspaces deleted?!?

When you type in my name on myspace, my old ones from middle school show up! i had like 4 of them, i had to keep making more because i couldnt get on them anymore, the pwords stopped working. so i cant log on and delete them myself. i havent been on them since like 2007! can i contact myspace somehow and have tem deleted? its really embarresing and i dont want colleges or jobs to see that..
