I see, it now all makes sense now!
The sudden police activities to hunt down and stop the leakers, is clearly the doing of Shueisha. But why now you may ask. The only reason would be, they don't want us to see what happens next chapter too early.
And as we all know Shueisha and Toei are working all close together and we know they hate Sanji. It must be the best Sanji chapter in all of History of OP and they are trying to stop it!!
