Me and two friends found a red keycard earlier, decided i would buy it from them and went on two more raids. First raid we instantly got headshotted from a name and situation that was nearly 100% certain a hacker.
Second raid same story guy could not know where we were but instantly headshotted us and knew location aswell. Added me afterwards and asked how much i paid for the red keycard that was in my sicc case. These hackers dont even care that they're showing they are hacking. I can upload a picture of the conversation but i have to blur our his name so whats the point.
