Is Idle Master safe?

Only if you don't use it with VAC-protected games.

it's safe.

so far.

To clarify what Zer0mega said, it's safe as long as you do not join VAC-protected servers while idle master is running

I used it on more than 200 games so far and I'm not banned.

I also used it while playing on a VAC server and I didnt get banned. Pretty sure its safe

It's safe. Also, don't use it while playing games, because cards won't drop.

Suprisingly it is.

Yes it is, but don't use it in VAC protected servers because that may or may not trigger it who knows but better safe then sorry. I have already got and sold almost 100 cards because of it.

I've used it before while playing tf2 in official servers and didn't get banned, it could be dumb luck but IMO if anyone says they got vac banned because of idlemaster they are probably looking for excuses

uh what does VAC have to do with anything, all steam sees is running another game

personally i use spacewar & just rename the appid manually

I've idled my entire 2000+ game library with it, sold the cards for close to $300, bought a Steam Controller solely on card money, no problems so far :)

The only suggestion I would make is to only run it while you're not playing anything (while you're at work, sleeping, etc.). Turn it off when you start to actually play a game.

I idled every day for 3 months straight to get all my cards, so it takes a while if you have a lot of games, but you can't complain about free money!

Totally safe. Didn't want to start using it but started to because my internet connection is usually crap and can't download games like a normal person and with idle master I can get the cards I need faster.

I never any problem w/ it.

Does it still work? I thought they patched it and it didn't work? Don't you have to play the game over 1 hour now to start getting cards?

it's open source, so anyone can go and check the code and see if it's safe or a scam, and compile it themselves if they feel that would be even safer, though if using the exact same compilation method the resulting exe should be exactly the same, thus one could in theory also check it that way if they're concerned enough

then as ppl have said already, don't use it with VAC games

I've used it for months, and hundreds of games, no VAC issues, and it won't steal your account info if that's your concern.

I've been using it even when DOTA 2 is running. No issue.

Source: personal experience, over 3000 hours in Dota 2.

It's very unlikely to get you banned, and for a good reason - everyone benefits from it - users, developers and Valve.

i would think if anything steam would like it at this point as it makes all your games look like you have run them for over 2 hours and you can then no longer ask for a refund for those games.
