Take the devs word for it: https://www.sportskeeda.com/esports/the-hacking-problem-valorant-why-cheaters-going-unbanned-riot-s-tactical-shooter#:~:text=%E2%80%9C97%25%20of%20players%20have%20never,by%20fewer%20than%203%20players.

I just got out of a game where my team was hacking. They were stack defending one bomb site in Haven every round, knowing where the attack would come before round start. It was a rare occasion that i knew 100% that they were cheating.

I refused to be part of it. And watching them carefully, I could see that in addition to a wallhack they had no recoil. But if they had aimbots on, I couldnt tell.

I've noticed a lot more of my own team mates cheating and I report a lot. If more of you don't report your own team, then this game is going to get increasingly infested.
