Meanwhile, Idle Master says a ban is unlikely, but you should avoid the program while playing a game that uses VAC.ĪSF's Github page states that ' not possible because ASF (unlike Idle Master or SAM) does not interfere in any way with Steam client nor its processes. The creators of ArchiSteamFarm (ASF) guarantee that the software won't result in a VAC ban. You thus might want to avoid running an idling tool while playing a VAC-enabled game. Although Steam will sometimes kick you from the game session, this does not prevent you accessing it in future. In terms of Valve Anti-Cheat System (VAC) bans, users have not reported such a ban arising from using idling software. In fact, Valve barely acknowledges the existence of this type of software. However, you can technically automate the idling process and earn trading cards as it is not explicitly banned. Therefore, you can't automate the listing, sale, or purchasing of trading cards. 'You may not use Cheats, automation software (bots), mods, hacks, or any other unauthorized third-party software, to modify or automate any Subscription Marketplace process.'
