account/channels ban question

Hello,

I know that with one account I can create multiple channels.
The question is: if I get a ban on one channel, the account and all the other channels are affected or the ban is just for the single channel?

What account you are talking about? Youtube?

well, I have a google account that I use also for youtube, but till now I used it just for my personal use (creating private playlist etc..)
I want to do YT marketing now and I have created 2 channels, if one channel gets a ban, the ban will be on that single channel or will affect all the other channels in the same account?
So..when a ban happens, it is on a single channel or on the whole account and all the channels associated?
