Idk, Seth
These fake leakers will cause trouble, it's just a matter of time. Looks like Shueisha tolerates spoilers until a certain amount/time, that's why we always get spoilers at the same day/time of the week.
Remember last year? The gear 5 chapter was leaked Sunday morning. It caused a LOT of trouble, Redon and Eten had to quit for like 2 months until things get calm, and internally in Shueisha, they had some people out.
That's why is so dangerous, they don't need to be right about the gake hints or fake spoilers. They just need people to believe, and Shueisha can notice that.
