What can you expect from Easy Anti-Cheat if it detects nothing and let this Bangalore play the entire game? He probably played on that account for a few more hours, maybe days, before he received enough player reports. EAC stopped detecting the simplest things, let alone Zen, Titan, Xim etc.
A few days ago, I was watching a streamer (very niche, only 2-3 viewers, but I checked it out of curiosity after I was killed by it in a strange way) who had something called jitter, meaning mouse scripts. When he shot, the crosshairs would shake slightly left and right (very fast and very regular vibrations). But I gave up on them, because there are so many cheaters here, you can't count them, bro.
