Steam Family Share / Login

Hey,

I considered buying for a month, but don't want to use it on my main Steam account. Now, I have Family Share enabled for my brother, and ONLY his account is authorized, but not my 'smurf' account, allthough it is tracked on what accounts logged in on this PC.

Does anyone know what happens if the smurf account gets banned? Will my main account be banned too if I log in?

If the smurf account isn't linked to your main by family sharing, it wont get banned.
