I have been waiting to reply to this plea to give you a chance to see my reply in the feedback section.
Juliette was not banned for building "near" another player. She went inside the player's home, built a lift to get on the other player's roof, and built a platform of cobwebs over the player's home.
A SrMod took Juliette into a channel to discuss the situation so it could be rectified without the need for a punishment. Juliette did not seem to want any part of discussing it, and instead of trying to work with the moderator, she pelted him in the face with enderpearls.
We understand she is young, but we would really like to see her have a better understanding of why this is not the ideal approach to working though a problem before we consider offering an early pardon.
