Read Lazycat's link. It addresses this.

Yeah. Keep in mind that it does vary,the record I had was 6 hours for one card. It was major bull****. Also had a few which dropped in as little as 30 minutes. So it averages out.

Approx 2 hours per card.

Alright, thanks I guess. xD I'm still a bit scared tho. Should I move my skins to my other acc just to be cautious? Plus I value this account alot so I don't want to have a VAC ban with a bad reputation and stuff.

If you want to, go ahead. I'd classify it as being excessive but it's your account so it's your call there. I've yet to see someone who hopped onto a VAC server while on Idlemaster get banned except due to other factors (Had one guy blame Idlemaster for his ban, but checking his history showed a history of using aimbots so it wasn't hard to dismiss him as being a liar)

If I'm reading this correctly, the answer is yes.

You're not the first to have done this, the other who did it were fine 6 months after they did so. It's recommended to avoid doing it due to a false positive maybe causing a problem, but assuming you're not running a hacking program in addition to idlemaster you should be fine.

I'm gonna start linking people who ask these questions here. This is just so nice and succinct.

Long story short, your idle master "car" has no petrol and you're yelling about how it's not driving anywhere. Steam cards are finite so you have to keep getting new card giving games if you want to keep idling.

You'll be fine. This has happened before to various people and nothing happened to them. You are safe.
