Just add a rel="nofollow" to profile and sig links. Problem solved :-)
<a href="spammed-site.html" rel="nofollow">Spammed Site</a>
Another method is to add this to your header script...
Code:
if(preg_match("/profile\.php/i",$_SERVER["PHP_SELF"])){
$header="<meta name=\"robots\" content=\"nofollow\" />";
}
Then simply insert $header in your HTML section.
