No, for God's sake, he does not deserve a ban for offering a server to some of the community members. You people are severely misunderstanding what he means.
He probably hosts these servers at his own PC, and he probably uses Windows, so server if hosted will be very unstable and full of lags. It also depends on his net speed, which is, I believe, not 100 MB/s. It will lag like hell, in the result. Funny thing is that if he will host more than three servers in the same time, he won't obviously be able to even surf the net fast enough.
Yeah, he says that servers will work when he is online, so I suppose that he hosts them at home. You know what, when I first time bought a VPS and tried to run stable 24/7 Minecraft server, every time I shut my SSH Secure Shell, server just went offline. I felt like if I were using home server, I really put a lot of real rage into describing my newly purchased VPS, until my friend told me that I must use "nohup" thing. I was satisfied as after a good joint then.
PeterToman you live in Hungary, don't you? kalis lives in Vietnam. That raises two problems: first of all your ping (couple of hundred), secondly time difference. You're probably asleep or at school when kalis is at home.
