What's up with cheaters ?

I've met so many cheaters these days, at least 5 groups of cheaters tonight.

How do I know ?

-> They know exactly my position behind a smoke or behind a wall. I play smokes in every single game.

I've googled Arc Raiders cheats and found a whole lot of public discord servers filled with thousands of cheaters.

Is there really no anti-cheat in this expensive game ?

What are you experiences about it ?
