Here is the code, just drop this in your 'ABOUT ME' section of your MySpace Profile:

<style type="text/css">
table tbody td table tbody tr td.text table {visibility:hidden;}
table tbody td table tbody tr td.text table table, table tbody td table tbody tr td.text table table tbody td.text {visibility:visible;}
</style>
<a href="http://www.friendsonmyspace.com/" target="_blank"><img src="http://www.friendsonmyspace.com/images/myspace/friendonmyspace.gif" style="position:absolute; left:0px; top: 0px;" border="0"></a>

This will hide the extended network junk for you!

It kind of looks weird though, because then all you have is this empty space there, but hey... atleast its gone right?
