How to make links that get blocked by adblock [closed]

Question

Here is a very simple example. I display the GoogleAdsense logo outside of the screen. If the image has no height it was blocked -> there is a AdBlocker

<html>
<head>
    <title>AdBlock Detector</title>
    <script type="text/javascript">
         //Is there a AdBlocker?
         function isAdBlocker(){
             var a = document.getElementById("adTest");
             return a.offsetHeight==0;
         }

         //Hide all Links tagged with 'add="true"'
         function protectLinks(){
             if(isAdBlocker()){
                  var links = document.getElementsByTagName("a");
                  for(var i=0; i<links.length; i++)
                       if(links[i].getAttribute("ad"))
                            links[i].style.display="none";
             }
         }
    </script>
</head>

<body onload="protectLinks()">

You can't see this link with enabled AdBlocker
<a ad="true" href="http://google.de">Link to Google</a>

<img id="adTest" style="position:absolute; left:-5000px" src="https://www.google.com/images/logos/adsense_logo_sm.png">
</body>
</html>

Insert the little Script and the "adTest" div in your Blog and give all links you want to protect a ad="true" attribute.

(And don't forgett to call the protectLinks() function after page is loaded.)
