# Optional
You could modify the volumizer class to generate functional javascript, but one that does not do anything significant. (making it much harder for profilers from detecting you are using a volumizer by creating legitimate javascript)
Remember: AI based profilers can probably understand what you are doing. Not effective enough.
Be creative.
