Filter tripfaggotry script

Is there any way of changing this greassmonkey script so that it filters out tripfags instead of sage?

http://userscripts.org/scripts/show/2124

Here's the source code:

// ==UserScript==
// @name          4chan Anonymizer
// @description   Make everyone on 4chan appear as Anonymous - remove all names, tripcodes, and emails other than sage
// @include       http://*.4chan.org/*
// ==/UserScript==

(function() {

         // Remove all linkmail (unless they are being used for sage) and postertrip elements

        var toRemove = document.evaluate(
            "//a[@class='linkmail' and @href!='mailto:sage']|//span[@class='postertrip']",
            document,
            null,
            XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
            null);

        var element;
       
        for (var i = 0; i < toRemove.snapshotLength; i++) {
            element = toRemove.snapshotItem(i);
            element.parentNode.removeChild(element);
        }
       
        // Set the contents of all postername, commentpostername, and remaining linkmail elements to Anonymous
       
        var posterNames = document.evaluate(
            "//span[@class='postername' or @class='commentpostername']",
            document,
            null,
            XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
            null);

        for (var i = 0; i < posterNames.snapshotLength; i++) {
            element = posterNames.snapshotItem(i);
               setPosternameInnerText(element, 'Anonymous');
        }
       
    function setPosternameInnerText(element, text)
    {
           if (typeof element.innerText != 'undefined')
           {
             element.innerText = text;
           }
           else if (element.hasChildNodes)
           {
             var childNode;
             var linkmailFound = 0;
            
             // Go through the child nodes - remove anything that's not a linkmail element.
             // If linkmail element is found, set its inner text; otherwise, create a new
             // text node for the inner text.
            
             for (var i = 0; i < element.childNodes.length; i++)
             {
                 var childNode = element.childNodes[i];
                
                 if ((childNode.nodeType == Node.ELEMENT_NODE) && (childNode.tagName.toLowerCase() == 'a') && (childNode.getAttribute('class').toLowerCase() == 'linkmail'))
                 {
                     setLinkmailInnerText(childNode, text);
                     linkmailFound = 1;
                 }
                 else
                 {
                     element.removeChild(childNode);
                 }
             }
            
             if ((linkmailFound == 0) && element.appendChild)
                 element.appendChild(document.createTextNode(text));
           }
    }
   
    function setLinkmailInnerText(element, text) {
        if (typeof element.innerText != 'undefined')
        {
             element.innerText = text;
           }
           else if (element.hasChildNodes && element.appendChild)
           {
             while (element.hasChildNodes())
             {
                   element.removeChild(element.lastChild);
             }
            
             element.appendChild(document.createTextNode(text));
           }
    }
       
})();

It's probably using some JavaScript thing your browser doesn't support (I'm using Firefox 3.1 nightlies, and haven't really bothered to test in anything at all that's been released, thought it should work in 3.0 and maybe even 2.0). There may be something useful in your error console or whatever your browser has.

It seems Opera doesn't support JS 1.6 "for each(var x in y)" notation. I'll probably do something about that fairly soon.

If it's working it should block the DIX/That was VIP quality! posts if it's repeated enough times, yes.
