I feel kind of bad for 'Deluded' but at the same time, it's truly a hilarious quote. Did you let him back in? Also, was he offline when you booted him? The added confusion plus the lack of seeing 'CoS out of that, asshole' only adds to the hilarity of the situation.
Deluded was our top rogue at the time, and a RL friend of mine. Yes, he was invited back to the guild though, if I remember correctly, he was out of town for the weekend and had signed back on Monday not knowing the story. Quite the 'wtf?' moment I am sure, but he had no fear of it being a real gkick because, as I said, he was one of our top raiders.
He just recently went into 'semi retirement' and now plays a hunter named Sneaks. He is still safely in Keen Formation, not having been kicked sense that faithful day that I got butt fucked by some rogue in arenas.
