Im not quite sure what you are asking but the report links are dynamic and written in a combination of PHP and Javascript:
<script type="text/javascript">
ob=function(o,q){return (typeof o==='string')?((o==='')?q:document.getElementById(o)):o;};
inr=function(r,t,u){if(!(r=ob(r))){return;}r.innerHTML=u?(((u===1)?t:'')+r.innerHTML+((u===2)?t:'')):t;};
if (__ossIsLoggedIn == 1) {
inr("reportlink",'<a href="<?php
$url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; echo $url; ?>&report=1">Report this video</a>');
}
</script>
