I can't really speak to the situation that occurred here because I haven't been around but in general I feel people are too quick to jump to the conclusion that someone is hacking. In Arma, there are so many factors that go into winning a gunfight vs someone that falls outside of who has the better shot. Most of the time desync + bandwidth + positioning determines who kills who. After watching some of 3 Rips montages and comparing that to some of the things I saw Symphuny do, I saw some weird similarities in the way they leaned + zoomed for most of their kills. It's not really a natural way (assuming relatively standard key bindings) to pull off the same lean + zoom every kill. I know Symphuny was so bad for that in his video that it became pretty evident that there was more going on. I haven't seen enough of 3 Rips to fully decide but I have seen him do it which is suspicious. Regardless the overall skill level on the server has declined significantly since the 3 server days, so if one player has invested that much time into the game they most likely will appear proportionally better. At the end of the day, the staff reserves the right to ban anyone from the server for any reason and there isn't much you can do about that (not saying it's a bad thing but having that power can deal with future potential headaches before they occur). The players who are constantly killing people will always be under the most scrutiny for this kind of thing but at the end of the day it's just 1 server on 1 mission file in 1 videogame.
