If you'd like, you can edit which bad words you'd like to censor ^. As you progress down the code, you'll come across:


$bad_word = trim( $bad_word );
if ( preg_match( "/" . $bad_word . "/i", $str ) )
{
$new_word = '';
for ( $i = 1; $i <= strlen( $bad_word ); $i++ )
{
$new_word .= '*';
Feel free to alter the filter from '*' to anything such as 'bobba' or '%@!*&' etc.
