Last night (around 12:00 am, Eastern Time US) a "vac hack" was used, at which point every player in the server instantly spawned/ appeared at the same unknown location. As a result, everyone that did not immediately alt+f4 was killed within a couple of seconds. This is not the first time this has happened either. It happened once around a month ago- everyone was sucked into Electro, near the hospital, and picked off by snipers. Again, a week later, every player suddenly appeared outside of a helicopter that was mid flight. The entire server, aside from those in the helo, fell to their deaths. It's gotten so bad that I've left the server for good.
