I kind of remember the first ban because it was my last day on the server and just went around and looked for smaller houses that had few belongings in them. I did infact grief the house, however I don't remember being confronted about the grief. I also got on the server, and I wasn't banned. Also I got on the server and the last place I was in I wasn't able to destroy, or steal anything.[For checking purposes]
The second one, I don't remember at all. I attempted to get on the server a few minutes ago, and it was down, so I wasn't able to the where I was last, or what the server had. But, around the second month I got my account my friend begged me to use it, I let him use it, and he did get on a lot of different servers. But I don't think you guys would believe that, so I'll just take whole responsibility for the grief, I would go and apologize but it was down.
The last server I was on which was FlamingCraft (which also had the heroes plugin), I did not grief on that server nor did I steal anything from it, all I did was PvP and train. Now that it's down, this server is my last hope of playing a server with the Heroes Plugin.
