Huh, so there may be some weird server desync issue right now that's causing false positives for hackers.
One streamer yesterday got really confused when he got shot over a full second behind full cover, but there was absolutely nothing suspicious about the other player's movement, aiming, or stats, they just aimed at a spot the streamer wasn't and fired.
Today, another streamer I was watching was playing a squad game, they see a player on the stairs in a 2 story on Erangel, he shoots at him but the other guy doesn't move, they just stand up and down and then get downed. The streamer got confused and finished him, and then the other player shouted NICE CHEATS BRO to his confusion. Then one of his squadmates suddenly said "Wait... were you shooting at a person? There was nobody on the stairs on my screen." The other player was in a completely different spot but somehow got rendered in the wrong spot for another player, and since it's client side hit detection the shots registered.
