Hi, I want replace some words in activity wall.
I use this code in bp-custom.php but doesn’t work.

function replace_content($content)
{
 global $bp, $activity_template;
 $wordlist = array("word1", "word2", "word3");

    foreach ($wordlist as &$word) {
        $word = '/\b' . preg_quote($word, '/') . '\b/';
    }

    $content = preg_replace($wordlist, 'censored', $content);
    return $content;
}
add_filter('bp_activity_entry_meta','replace_content', 9);

Any suggestion for proper code?

Thank you.
