You maybe could change:

PHP Code:

                $text = preg_replace("#$censorword#si", str_repeat($vbulletin->options['censorchar'], vbstrlen($censorword)), $text); 


to

PHP Code:

                $text = preg_replace("#$censorword#si", " $censorword", $text); 


There is also another preg_replace() line above that where you could make a similar change although I'm not sure if that would do what you want.
