Haha, I literally laughed at your post. I figure it was due to how fitting this is with your character: "I'm only leaving if Kainzo makes everybody else a target. Then I'll come back and harass people around the shop more". You can call your method of play hardcore, and before the mud-slinging and singling out individual users you are even operating within the bounds of the rules. But once you start catching the ire of the administrators for it, it's time to shut your collective logorrheic mouths and go away.
I'll reiterate- I don't hate you. Not seriously, at least. You're whiny and immature and spiteful, but not worthy of my hatred or that of anyone else. I dislike how you and your company portray yourselves online (eg, as a particularly tenacious brand of internet tough guys) and am beginning to tire of you being the news of the day, and as a result would like to see, hear, acknowledge less of you. I look forward to the day when Airbus' shop is deserted but for the KoK sympathizers that stay nearby, keeping a vigil with /hero who and tracking you whenever you log on (y'all can have that idea for free). Or when your key members are permanently banned or otherwise dealt with due to their own irreverence for the server and it's inhabitants. Perhaps if two or three were so punished, the others would take a hint. But then again, maybe not. It's my experience that the younger teens tend to be the most oblivious and self-absorbed.
Now, that's out of the way. What do the Tree Creepers, or you (observing that you act like the ringleader) have against public projects? Too much sense of community? Not hardcore enough? Maybe you'd rather have potential experience fodder running through lakes and forests so you can kill them before they can get away. Quick railways and general infrastructure would mean you actually have to set up an ambush, rather than just using sneak when you see somebody coming.
I maintain that your presence and mannerisms (because until now you've been unwilling to alter those) would be less inflammatory elsewhere- in ascending order, a different area of the map, another Minecraft server, or a server for a different game where improvement and development are not factors.
