I was called a hacker by some serious people back in 2.01, I was having a really good game as a skulk and I kept ambushing groups of two or three marines.
Also, one time on LM (which I just now remembered and chuckled at), on ns_caged, I heard a skulk somewhere around me in Stability Monitoring, sneaking about. I, being my kharaa self with knowledge of good ambush spots, decided to check above the ladder that leads up to generator hive. I hopped on, got halfway up, turned on my flashlight and shot the skulk that was sitting there. The kid freaked out, constantly making comments for the next 10 minutes about how I "absolutely use wallhacks, nobody coulda ever seen me there..." on and on. Fortunately at the time, somebody (I think Smoke_Nova?) had been spectating through my eyes and seen the whole incident, so he was laughing at the kid along with me. :lol:
