There have been a lot of players cheating in Rust as of late to try and help them survive because they suck at the game and now Facepunch Studios have got fed up of waiting for the Steam anti-cheat system to kick in.
The problem they were finding with VAC was that it wasn't fool proof - and that it could take weeks or months for cheaters to be banned in waves, which wasn't good enough for Facepunch studios.
They didn't want to install something like Punkbuster (which sucks as it is), and so they built their own system over the weekend and since then they have issued over 4,500 bans to players - which won't be overturned.
As this is still in the testing phase it is only applied to the official Facepunch servers but server owners are welcome to run the server with the "-cheatpunch" command line.
Garry Newman said that if you're caught you won't be unbanned.
If you get kicked from the official servers with the message that you’ve been banned then you have been caught.
You’re a naughty boy. You know what you have done. You won’t get unbanned. We know it was your 9 year old cousin. We know your computer got hijacked. We know that the CIA is getting you banned from all your games on Steam so you will join them in the hunt for aliens.
We fully expect cheats to be touted as ‘CheatPunch proof’ quite soon. That’s cool. We’re never going to be finished fighting.
The eventual plan for Facepunch is to setup a website where banned players can see the evidence of why they are banned.
Hopefully this goes towards fixing what is a very big problem in survival games such as Rust and DayZ.
