A wordpress text censorship plugin

found this on the MU forum, don’t know if it would require tweaking or not

<?php
/*

function fix_bad_words($text) {
    $bad_words = array(
        'bad' => "%#$!%$",
        'bad word' => "%#$!%$",
        'worse word' => "%#$!%$",
        'very bad word' => "%#$!%$",
        'much more badder word' => "%#$!%$",
        'anything' => "%#$!%$",
        'really' => "%#$!%$",
    );
        foreach ($bad_words as $bad_word => $fix)
        $text = str_replace($bad_word, $fix, $text);
    return $text;
}
add_filter('the_title', 'fix_bad_words');
add_filter('the_content', 'fix_bad_words');
add_filter('comment_text', 'fix_bad_words');
