@Brian, It is not as you are thinking it to be. Internet at our home is used by every fellow member since very the beginning. That high ping spike, high lag is NOT caused by that WiFi. Because, Whenever I play, I am not alone using the internet. Nothing goes wrong. WiFi only causes my ping to be from 160-70 to 200-21. Thats not a big difference indeed. Even if I had WiFi turned off, This wouldn't have made any difference. There are very very much less chances of my ping to go high > 250. As I told above, Here in Pakistan, Such Internet issues are common. Normal ping spike happens. When I join server, everything is fine. While I play, everything is fine. Just sometimes a ping spikes causes it. That is, NOT INTENTIONALL NOR ARTIFICIAL. Btw, If I was lagging/unable to play. He first had to warn my by words to fix my internet. Than by command. Later on kick was aplicable. And than, ban would have been considered as legit. But here the scenario is different totally.
Let staff make decission. I'm sure they aren't in need of your point of view.
