Ok, it turns out that I have been banned for supposedly killingfarming, I understand that doing that is not right, but I never tried to do that, it was not my intention and I don't know why I would want to do it.
As you can see in the video, I am killing that player several times, but it is only the beginning of the game and in addition to the fact that I had no peak, he tried to equip himself again to kill me, and in fact he succeeded on one occasion, for that's why I thought I would cover the iron generator and then chop the obsidian without bothering me.
As I have been banned for 7 days and my appeal has been rejected, the only thing that occurred to me is to make a thread here, I do not know if someone can recommend what to do or I do not know ... I really like this server, to be banned 7 days is not the biggest problem but I don't know if it is worth playing again when I was not trying to do anything wrong.
