My friend (whose name shall not be said due to privacy rights) thinks he can use cheats offline on Team Fortress 2 without being VAC banned. I think that he will still get banned for this. He then proceeded to tell me that if Valve cares so much about hacks then why would they make it so easy and simple to enable the developers console to do so.
I am just really confused and need somebody who knows from credible experience of this subject. Can you get VAC banned for using cheats offline on Team Fortress 2?
