Zombies Question

If you hack on zombies online where you play with 4 people will you get banned or is it safe to hack on online zombies with 4 people. I already know that if you hack on solo zombies you won't get banned, I'm just wondering about online (4 people) zombies mode?

Everything running through the Single-Player BO is not running along with VAC. Only if you start the regular MP, VAC will start.

so i take that as you can hack in 4 person zombies and not get banned thank you
