JarateKingBBiA_duchessAll valve needs to do is take a lesson from Blizzard. if you cheat, your ip is perma banned for life. You can't get a new account or any of that shit.Iirc it's in steam's ToS that VAC bans are linked to the account and are only intended to block that specific account, and not the user. You don't break any terms of service by making a new account after you've been banned.
Idk if there's a legal reason, or if it's just to stop all those people arguing about their friends using cheats once, but we're not going to see any ip/mac/hardware-id bans any time soon unless valve makes a U-turn in their banning philosophy.
Don't they ban all accounts linked by a phone number when one account is vac'ed
