MySpace.com has a removal process that requires you to send a request to remove the profile. A response is sent to the e-mail used to register the profile account initially. As long as that is a valid e-mail address and isn't blocked by SPAM filters, this process works easily. You can view this process herethrough this video file.
If this doesn't work, I have worked out an alternate process with MySpace. You can listen to the instructions for that here
be safe,
