Nozaki is not Undu, Nozaki just went and cried to Undu(former admin) about Kinochet bullying him, and Undu told him to stop tagging Nozaki(on his Poast account).
Nozaki made his own instance and was in a thread this morning, someone on Chudbuds asked why they couldn't see his posts, and so Kinochet told them because he was defederated(at his own request) so that he could still engage in threads they're in while they couldn't see him. For the high crime of replying in a thread Nozaki was already in, he is now banned and defederated. Not unhinged behavior by an admin that should make people feel perfectly safe to remain on Poast.
