I was accused of xray modding by Rezonl, and I admit that I did use an xray mod at one point in time when I had first joined. It's only a small portion of what I did on the server though as most of the time I was working on a house of mine in the wild. Your server is one of the only servers that I really enjoy playing on, and I promise that from here on out I will never again use a hacked client.
Actually, I suspected it, and Sios was the one who banned you. However, how can we trust you that you weren't using the x-ray throughout the rest of the time on the server? While you were building your house, maybe you turned on your x-ray to mine some iron ore nearby. As well, you were constantly warping to spawn after a super-moderator logged in. Anyways, if you do get unbanned, there will be a heavy consequence attached.
