If you have a VAC ban on your account, you're prone to cheating.
You should not play games with me.
Almost all the cheaters I've encountered had VAC bans on their accounts for other things. The devs should ban anyone with any kind of VAC ban from playing.
And your friend lied Johny. The only way to get VAC banned is for steam to detect the signature of a cheating program and then ban you with a VAC ban wave. If your friend has a VAC ban, he was most certainly cheating.
I understand where you are coming from but that's not always the case
you don't have to cheat to get a ban, there are a such thing as false positives + password security back in the day isn't like it was
what about people who haven't had a ban in over 300 days? They're obviously not cheaters at that point. If they were they'd have had under 200-300
If I accidentally got a VAC ban I'd understand I now need a new account. You're not actually supposed to share steam accounts, if you tell them you were account sharing they might steam ban you. The reason is because they want each individual person to buy their own games. So if your friend was using your account, you guys were technically cheating in another way.
you don't need to share an account purposely for another to use it
you don't seen to have understood previously that "Shit just happens"
and what's wrong with sharing a steam account so long as you trust said person? Should people get a ban because they shared a video game? If they get your account banned it's your account but you knew the risks.
