I do not have any video or pictures because I left the game immediately after discovering it. I forgot to get the exact time but this happened at approximately 3:20am GMT +/- 20 minutes. As a "serious" adult player, I am cautious and not a bandit. I wasn't out looking for trouble. Here is the encounter: I was way up north. I ran into this guy seemingly out of nowhere in the middle of a field. I then proceed to say "friendly"; he also said "friendly" via voice chat. He said that he'd put down his guns. He said this because I told him to keep a distance from me. After all, he wasn't shy about shooting in my direction repeatedly, but he either was a really bad shot or was just trying to make me nervous. He didn't have a bandit skin, so I wasn't sure what he was doing. He put down his guns but insisted on chasing me around for the next 30 seconds or so. I told him to keep his distance, and to stay 10 meters away from me. I told him that we could talk from that distance. He said ok and complied for about 10 seconds. I kept running around because I could tell there was something screwy about him and he didn't seem sure about what he was doing. He then started to run toward me and proceeded to trespass on the 10 meter distance. I then told him to back off multiple times. I then asked him what he was doing, twice. Both times he replied, "I'm looking in your bag." I told him to stop. He then removed a gun from my bag. I then opened fire with my AK. I have a low ping and could easily hit him. I was watching the blood splatters fly off of him and was hitting him with about 50-90% of my shots. I unloaded two clips on him at point blank and then told him that he was obviously a hacker and that he was going to be reported. He apologized (like kids do) and insisted he give me my gun back, but I didn't check what else he may have taken, because as soon as I got it back, I logged off. By the sound of his voice, this was probably someone aged 8-18. Obviously he was more interested in harassing me than killing me, but obviously was using a cheat not to die.
