I almost guarantee it was related to the Chinese harassment. Flare had talked about on stream before that Coco was hit hard by it and blames herself for the antis spamming. Even to this day the mere mention of Coco in some girl's streams brings spam from them flooding chat. Like what happened with Suisei a few weeks ago when she dared to do a Coco impression.
God thinking back to how barbaric some old medical practices were, this stuff must have been a slaughterfest of chopped dicks and tits all over.
