So, for the first ban, I remember quite good, because I was playing on really good server . It was one of the most popular servers then, and it was a lot of fun. Sadly, there was a lot of plots used so I accidentaly came by one house that wasn't claimed. So I decided to claim it. Everything was going fine, I decided to redecorate it. I started expanding, building farms and everything. But one day, about a week or so there came a man and said that the house was his. Of course, I didn't want to give it back and he said that to admin, apparently they were good friends (in game probably), and the admin said it was griefing, so I got banned. That's the story.
Now, about the second ban. It happened in a really weird way. Me and my friend where playing on it. It was a pvp-hardcore-raiding-factions server.
Well we raided some factions got geared up and then attacked some people. And it was impossible how that man survived two diamond geared, fall from a high mountain and lava. We started chating with one of the admins and he said that they have all in game enchantments level 127 on their armor. Me and my friend didn't believe that, until he gave us some samples of that. Of course we went and used them to kill other people. Those people Said admins how could we kill them, apparently they bought that stuff. And other admins(not that who gave us the armor) thought that we somehow cheated those in and we got banned.
Sorry for such a long text, hope it explains everything.
