This is so funny because rust has one of the worst cheating situations and majority of their players are windows users, and theres lots of games that have anticheat that allows linux and have notably less significant cheating problems like marvel rivals. in reality rust doesn't take cheating very seriously because if they did they would have more server side software that detects illegitimate behaviour like tons of other games do successfully...... even most popular Minecraft servers have better functioning anti cheat that is completely server side than rust has while getting kernel access to your pc. its pathetic and lazy development tbh and this entire post from them reads like such extreme cope....
Maybe I'm wrong but the server could read where the players are and what are they don't and see if they can do that without using cheats. Then you keep the statistics of every player and flag every time there's something strange. If too much flags raise, check the user. I don't see the need to do it in real time. Some games will be bad... but nothing stops the server from rescoring the game after checking if a cheater is detected. The server can even send an alert to the other players of that game and let them decide how to fix the end result of the game.
