I was the victim to many of the lives taken by my good fellow Bruno over here. I don't have any video evidence or an admin POV, but I can say that when I was getting slaughtered by this man, I could see pretty clearly that he was hacking. Found it very odd that he could see me through one-ways and could also very consistently hit head shots on me and my, now fallen, comrades. I wasn't surprised when he got permanently banished to The Pits of the Gmod Menu Screen and I, from a law abiding citizen's point of view, think that it should remain that way.
