Solved❓ VAC Bans?

I got into a bit of an arguement today with a friend of mine over hacking and banning and such, He was trying to tell me that if you Hack on an ALT and it get VAC Banned, that VAC Ban transfers over to any account on the same machine the hacks were on, is this true? I told him it wasn't becuase a friend of mine who also hacked on alts to boost and sell them has had many alts VAC'd for cheating and yet his main which is Global is still not banned. I'm only worried because i dont want my main to be VAC'd, and if what the friend of mine was saying is true, i plan on removing all of my hacks from my system and just not messing with it anymore, any input from you guys would be great! thanks for your time.

No, you would not get all other accounts banned on the same system, you would only get a ban if you used hacks on all accounts and it was detected or you were caught by overwatch. No need to remove all hacks from your system, they wont do any harm unless they are running.

No you're safe until you flag the account by connecting to CSGO with a already running hacks in backround
