VAC probably has one of the best detections I have seen in an anti hack. The only downfall to VAC is that it is never an instant ban. VAC bans can take between 1-2 weeks after they stealth update their detections and catch your system running a detected hack.
People say VAC is bad, but in all honesty they put up a great fight. The best part is you get your steam account in general banned from playing rust ever again. Most of the time people will just buy another copy and continue hacking.
Having an rpg element to the game obviously is looked down upon, but it would be nice to have for hackers sake. If you get banned on your “main”, there is literally not a single difference than the account you lost than the new account you just bought other than things you’ve researched which can literally take approx one day to find everything again with some friends help of a research kit.
The reason hackers are so relentless is because they literally lose nothing within the process of getting banned other than money which there are some people who don’t give af about the money lost. Welp got banned, buys another copy, back to hacking.
