Can mod bug cheat kicks cause a VAC ban?
Hey, sadly I have to play on a heavily modded server of a friend and get cheat kicked a lot due to bugs. Is there a risk to get a VAC ban from it or is it a separate mechanic?

Client side modifications such as lua, textures, sounds, maps, etc will not result in a VAC ban, but you may fail the extra server-side checksum check. Being kicked from developers custom "anti-cheat" features due to mod use will NOT result in a VAC ban.

Also if you use "-nosteam" VAC will not function, nor will steamworks sdk, so you will have a game similiar to GOG (compatible with GOG clients provided you're not in a BETA as far as I am aware GOG has no such betas available)

VAC bans only can be given by VAC secured games, PZ is not VAC secured.

But there is an option for VAC in the server option. Someone said it's for Steam servers only.
Maybe there is an option to autokick someone who has a VAC ban on the account they use to connect with but there are no VAC bans for someone kicked by PZ's anticheat.

Hey, don't be rude please. Not giving the reason for a belief is not the most efficient, but the same goes for your belief that all games would have it.
I don't know whether the Steam library included in most games includes VAC functions, but unless included or the function called, I wouldn't consider them protected :)

very stupid reasoning on your part. absolutely all games are protected by vac, it's just that it is not configured correctly in every game
You are wrong, Project Zomboid is not a vac protected game. VAC is optional for dev and they are not enable by default.
The author of this thread has indicated that this post answers the original topic.

In most cases, all sides are more or less accurate to some extent, which is why reasons for ones information/belief and being open to others are important.

Default option in the pzserver.ini for dedicated servers:
# Enable the Steam VAC system
SteamVAC=false

While I did not report your hurtful behavior, I hope that you can learn that we have reasons for everything we do @GILMUT. School and TV train us to believe in winning "arguments", while it is a very dividing world view.

In practice, I had been kicked due to a mod / false configuration once, because a certain anticheat feature was forgotten to be disabled, but did not receive a penalty.

So no, you can’t be vac’d for cheating at the moment. This may be subject to change in the future, but It’d have to be something far more serious, if it were to happen.

What happen the previous VAC enabled state?

I'm the one who specifically asked the devs for VAC config options on the old PZ forum that got archived when VAC was introduced, and got attacked by the community for asking something basic.

You mean that VAC was never -enabled- despite it previous introduction and CURRENTLY stating so? If there is no VAC, the game shouldn't report VAC enabled to clients, NOR should it actively report VAC enabled status in the console of the dedicated server. These "bugs" should be fixed if its not actively used. They give false pretense to protection from third party game modifications.
