Well, if you are playing FPS for a while, you might know the youtuber Rogue-9.
Anyway, he did a video about cheaters in BFV to denounce the fact that there is no anti-cheat (or at least one that is working) in this game.
The situation looks worst than what i thought.
I have already encountered average+/good players that seemed not legit for me.
Seeing a guy going 50/10 when every other top players have 30 kills, i know it is possible that something is wrong, especially when you see this guy running around all the time getting 3 kills/minute during the whole game.
Note that the developpers didn't respect their engagement in fighting the cheaters...
Here is the video :
