There was an -insecure launch option added to Rust a few updates ago. This means that there will be a tiny handful of servers you can still play on. The majority of servers are covered by VAC and you cheated on one. Even if you convinced yourself what you did wasn't cheating, you still altered the game files or manipulated the game's running memory, which is hacking and is always a cheat.
I am so going to host a server for cheaters only
I would pay to watch cheaters duke it out with each other all hacking.
