Pretty sure you can drink on both but cb doesn't allow you to get wasted as consent becomes a problem after that, if I recall she got wasted and possibly passed out on cb and they suspended her. Then she freaked out on them and moved to mfc and cb almost immediately reversed their decision but she already got all her followers to abondon them. And since she used to one of the top models mfc used this to get followers. So she can pretty much do whatever she wants now.
