Hacking has been a problem for most first-person shooters, and Warzone is no different, and in the height of its popularity, cheating was the main reason a lot of players quit. Eventually, Activision implemented RICOCHET which somewhat works.
It's not perfect and players still go unpunished. But it can be funny to watch as well as the game will actually start to troll cheaters before the official ban. Bullets will stop registering or they'll be placed in lobbies with other cheaters.
Both JGOD and Toronto Ultra streamer Royalize showed off some rather suspicious clips.
One tweet even showed the RICOCHET program apparently working.
His bullets appear to stop registering, doing no damage to the enemy player allowing them to snag the kill. RICOCHET is meant to foil a hacker's ability to secure kills. It would appear that the player did more than enough damage with his weapon in the clip to take down the enemy, but instead nothing happened.
Twitch streamer Bustbeforetrust denied allegations saying in response to Royalize, “Sir I don’t use aimbot think what you want IDC honestly I know my skill and potential.”
