I'm blockbuilderboz (recently Quantum_Doge) and I was banned about two years ago for griefing glowstone. I now post this appeal because I really like Build at Night and I wish to return to it. There is no other server like Build at Night that I have admired and now that I have had time to ponder what I have done, I think that I must never repeat my mistakes again.
Many of my favorite moments on Minecraft have came from this server and looking back, I see that greifing was a very childish thing to do, but I believe that I have matured now. My decisions as a teenager were poorly thought through -- there's no denying that.
Addressing the second part of the question, I feel like I have had a positive impact on the server(aside from the griefing). As a friend of FweFwe, I have helped contribute to a part of his town, one example being the-hard-to-miss Eiffel Tower or another such as . Thus, many of the projects we had in mind were either for the entertainment or benefit for all players on the server. As a player myself, I often traded with other players on the server and many would agree that I was a generous person as I sometimes gave away tools or resources for free.
Finally, I promise I will not repeat my mistakes twice. This is the only server that I ever want to forever take part in and repeating my mistakes again would be devastating to me.
Thanks for considering my appeal and I hope you accept my apology.
