Translation of tweet:
We are reporting violations by those involved with the VTuber agency "Nijisanji". The damage mainly involves taking secret photos of VTubers who hide their faces while working and disseminating the photos to third parties. They also send messages that make fun of their appearance. The fact that such people are in the industry will lead to more victims, and since the VTubers themselves are unaware that they are being secretly filmed, the photos will be made public on a live broadcast at 10:30pm on Sunday, September 1st, due to the accuser's convenience.
Man, what the fuck is happening in Nijisanji?
From the bunch of details I can put together, Kore Kore is alleging that a Niji staff member has been secretly filming and taking photos of talents without their knowledge and sharing them to a private group chat where they insult as well as slander them.
