Well i added jshackles last night, my intentions were to praise the software and ask the same question, but after doing some research i got the answer.

I started using Idle Master yesterday and by accident i forgot to close it and joined a tf2 vac secured server, i realized 5 minutes later that i didn't close it and got a little worried.

IMO there is no risk by joining a vac server while idling in a game, basically all that it does is run a game, pretty sure vac has nothing "suspicious" to detect since it's not connected with TF2 itself or any vac game in particular, but even if that might be the case it's best not to join any vac servers while running it, as the owner of it recommended.

Quotes from jshackles
"Finally, I don't recommend playing any Steam game that connects to a VAC enabled server while Idle Master is running. Although nobody that I'm aware of has been VAC banned for using Idle Master, it's better safe than sorry."

"This is not recommended, as having Idle Master running while connected to a VAC secured server is the only possible way Valve could detect that you have it running. I doubt that they care, but if they do this is the only way that you could be punished for using Idle Master. To my knowledge, nobody has ever been VAC banned for running Idle Master."

I regret the small mistake of forgetting to close the program before joining the server, i really hope this won't have any consequences, normally it shouldn't since nobody got vac'd by this in the past so hopefully it won't happen in the future, i definitely learned to be more careful and gonna double check from now on.

Once again, gratz on the software, this makes any game collector/badge collector's life easier.

Guess I'll mark this thread and check from time to time to see if you're VAC banned or not in the coming weeks. :P

The OP had the incident before me with 6 days FYI if you want to check, but it will be in vain as there won't be a VAC ban, Idle Master is anything but a vac detectable cheat since it's not a cheat in any way, but a game launcher.

Valve has a lot to gain with this software since a lot of people will just idle their cards and sell them on the market, and more sells means more fees, means more money in the bank, all parties have to win, the card provider, the badge collector, and ofcourse ValvE.

So the possibility of Valve banning it's users would be off the chart IMO there would be thousands of users getting banned and i'm refering to those who spend big piles of cash on the market, for absolutely no valid reason.So yeah, i wouldn't worry.

This post has the 2 proof of you are not getting banned by vac :D cus it's been 2 weeks and nearly 2 months so it's very safe to be accurate, just don't use it on vac... @Testyjanna Today, the same happend to me aswell. Seeing you not got banned makes me feel safe :D

both op and 2nd poster are still alive guess idle master is completely safe.

I guess is super safe 1 year later and no vac bans at all
