HelpNeed to knowledge about Vacs/Phone#/Mobile Auth

anyone here have knowledge of vac bans with mobile authenticator?

I have a question that i can't seem to find the right answer to. I have 5 legit accounts that are all tied to different phone numbers, but authenticated on the same device. I want to add a new "Hacking" account to the same mobile authenticator device but with an entirely new phone number. If that phone number gets banned, does it ban all the accounts with just that phone number, or all the accounts on the device the autheticator is tied to?

Sorry about the retarded subject line.. should say Need SOME knowledge..lol

So, in general you do not want your phone number OR authenticiator associated with a hacking account. You are taking a risk, on the hacking account I wouldn't even be using steamguard.
