no we dont need another system then vac, vac is clever and also the delayed bans are very clever but i guess you dont even realize why!
let me explain, a coder releases an uberpwnzerhaxxerleet injection, people are using it, for 1 day, 2-3-4 even 1 week and are telling others "yeah its totally undetected" and the failtrain starts.
vac is marking all of them and runs the wave ban on ALL of them that are using a specified hack.
if vac would ban within one day it wouldnt be as successful as it is!
hope you see the advantage of delayed bans
Okay that is fine that VAC does that, but what good does a delayed ban do when they are on the server at that moment completely ruining the game and work that you have done for hours or days? Just seems a bit dumb.
