Depending on the ban I’m not sure.  You would have to check with support, but from my understanding the tokens get frozen when a ban occurs.  I haven’t heard of someone getting banned for broadcasting on two accounts, but it could be a hidden rule, though highly doubt it.  All depends what you were doing on cam to be banned as there’s quite a few rules.  Please check the posts here for all the rules I’ve come across and see if any of them could be it.
