Since the abuse filter does not work on answers sites and Wikia won't fix it, we made our own abuse filter.

Here's the code: You just need to change var badwords.

/** ABUSE FILTER V2 **/
;(function ($, document) {
    'use strict';
    $(function () {
        if (!$('#article_textarea')) {
            return;

        document.getElementsByTagName('form')[1].onsubmit = function onsubmit(event) {
