The supposed leaks are fake, Miko said as much here without going to detail: https://youtu.be/Yu3Xj37zdzE?t=643

First of all, there's the Shiraken = Shirakami Kensetsu ”leak” which is self-debunking. No actual Hololive employee would make such elementary mistakes as it consists of, but it speaks volumes that the antis actually think it anyway plausible.

Secondly there's graduation guesser who predicted Chloe's and Fauna's graduations, except she didn't predict Fauna's graduation, she made it after Fauna had put up her announcement frame but before she streamed. Antis insisted that it's impossible that a JPschizo would notice Fauna's frame in time, but the entire reason we know it happened after is because of timestamps as every Japanese Holo general started doomposting the moment they got their alerts of an upcoming stream.

Also, this ”leaker” got the Chloe graduation wrong the first time, she then insisted it was postponed and her second guess proved to be correct. After that, the ”leaker” proceeded to predict a number of Holo graduations none of which happened while failing to predict any of the ones that did happen, until she got Ao correct although the date wrong. The supposedly new information in the Discord screenshot the same person ”leaked” in fact contained only things Miko had talked about days earlier. However, the antis who spam these leave out the wrong guesses and concentrate on drumming up the time the ”leaker” got Chloe correct and insist she got Fauna also.

See you fellas for Minecraft later
