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));
           }
    }
       
})();

Op here. I guess I should have tested this script before making this thread. This script doesn't remove post that have sage inside of them. Instead it changes the sage post to non-saged post. I assumed that it was capable of removing the post from the board entirely.

Is there any way of changing the script so that it removes the post from the board? If that's not possible, is there a way to make the script hide and/or alter the post if it has a tripcode in the name field?

For example. If the name field has the username "Desu!3s23ff5r7" it will change the post field to blank. It will be a script that basically ignores the post of tripfags. Such a script would revolutionize 4chan. So again, I'm begging you to create it.
