I've been on the receiving end of these cheaters, it happens, it's infuriating though.
I've been tempted to buy a PS5 for the sole reason of no cross-play in warzone.
Any one who has ever played an esports title online has been victim of cheating. PUBG is a lot better than it used to be, but it used to be weekly my pal Dave would report people and see them get banned.
I'm sure there is still cheating going on, but if it is then it's harder to spot. Which I doubt, as with time the game has become more secure.
From what I remember you can load and run cheats on a console, so you're not safe there. Even PUBG mobile has hacks.
