I don't recommend running Idle Master while you're also playing another game that's connected to a VAC-enabled server. Doing so is the only possible way that Idle Master could potentially trigger a VAC ban, and it also reduces the drop rate of trading cards pretty significantly. To be 100% safe, please close Idle Master before connecting to a VAC-enabled server. The program itself will never communicate with any of these servers, thus it is safe to use Idle Master to idle cards from VAC protected games.

this mean just quit idle before playing the vac protected game like tf2 and dota?....
and btw can i do other things like trade, marketing or etc..??

I start to use idle master today...hope no VAC ban to me
